NJ-DMV Interchange

 

Dispatcher Office ready to go. You can se the schedule, train sheets and bulletin. 

I hosted an operation session on Friday for visitors from New Jersey. Tom Piccirillo, Andy Brusgard, Tom Schmeider and Mike Quinn arrived at the house for an afternoon session.

I found it interesting that 3 of the 4 operators were retired police officers. Andy retired after 52 years of service. My dad was a a police officer for the Port of New York Authority, so I feel a kinship with policemen.

Op Session

Tom P. and Andy arrived early so I assigned them train 8 from Falmouth with engine Haupt. We operated under the rule that trains originating from Falmouth with scheduled meets at Brooke are limited to 8 cars maximum. So they left Falmouth with 8 cars.  

Later Tom S and Mike are arrived. They took Train 7 as soon as they read the bulletin.  To their credit, they had read the advanced paperwork and pretty much knew what to do as soon as they arrived despite being first time operators on the Aquia Line.

Train 8 arrived at Brooke for the scheduled meet before 7.  Being the train in an inferior direction, they had to wait for 8 to arrive. It was interesting that 7 needed to pick up a car at Brooke and 8 had a car to drop. So, the crews coordinated their actions to expeditiously do the job. 

Andy and Tom P - both had operated here before
Train 8 continued on but forgot to drop off two cars for Stoneman's. They decided to take the cars to Falmouth, vice flagging and backing up to Stoneman's, and then back haul them to Stoneman's when they departed Falmouth. This is not ideal because now the drop required a facing point move and they had to use the extended couplers on the nose of the engine. The extended links are more difficult to use than the regular link and pins, but they got it done.

Meanwhile, train 7 arrived at Aquia Landing. Unfortunately, at that point engine Haupt started to malfunction despite running fine beforehand. After some unsuccessful debugging, we switched engines McCallum for Haupt, and they attempted to finish their run. They assembled the train 9, but never did run it as they ran out of time as they had to leave to check into the hotel. 

Mike and Tom S.
The dispatcher annulled train 9, but Tom S. and Mike wanted to stay and finish their run with train 10. I have noticed in the past few sessions that the longer trains that we now run take a lot longer to work. I may need to adjust the schedule if we continue to find that the scheduled times are insufficient.  The link and pin couplers definitely slow down the process, especially for new crews.  

The random events procedure worked well. The crews pulled three cards. Two were minor events with no operational effect. The third card for crew of 10 required them to stop at Potomac Creek for 10 minutes to load troops whose enlistments were expiring.

Other than the Haupt issue, the ops session went well.

Mat Thompson hosted a group dinner at his house on Friday night. The group dinner is always a highlight of the NJ-DMV Interchange weekend. Mat's layout is also a nice treat to see too.

Open House

On Saturday I hosted an open house for the NJ-DMV folks plus local friends. About 15 folks arrived to se the layout. John Steitz, Mike Spoor and Amby Nangeroni ran trains while the guests looked around and asked questions.

Alicia made chocolate brownies which were all gone by the end of the open house

Problems

We discovered that Whiton, one of my  Mason engines with battery power was sparking on the tender trucks. The engine continued to run despite the sparks. The shorts on the tender trucks is  a common problem with the Masons from SMR Trains.  It may be due to the insulating paint wearing off the brass parts as the engines operate. Charlie Taylor also reports similar problems with his SMR Masons. I need to add insulation washers to all the Mason engines. I am also thinking about making make new 3D printed resin trucks for these engines. The resin will help eliminate some of these intermittent electrical shorts. Also, Engine Oscela has a broken wire to the front truck that I need to repair. 

John Steitz reported that the passenger car was picking frogs when he was running. It had not been doing that when I ran it, so I need to check it out.

Crunch Time, Again

 The NJ-DMV Interchange is scheduled for this weekend. So local layout owners are in crunch time getting ready for the meet. I have been doing some tasks to help others to get ready. My layout is ready to go except for some minor repairs such as a broken switch stand from a last op session. 

One of the embellishments to operations on my railroad that I wanted to get done was to make random events cards.  I wrote about this idea earlier in this post


Last night I printed a set of random event cards. Most of them involve delays of some duration, longest is 15 minutes. A few require cars to be set out. About one third have no operational impact. 

I am trying to decide how to trigger the random event.  For now, I am going to place them near Brooke Tunnel and Stares Tunnels. Each train will draw a card when the pass Brooke going southbound or Stares Tunnel going northbound. That why I can have one box near both tunnels to house the cards. I am curious to see how they work out.



Meanwhile, I have been helping Marty McGuirk with building the paper mill for his layout.  

About 2 months ago I helped Marty with a redesign of the paper mill area of his layout to better match the prototype he was trying to model. The drawing shows the design I proposed to him.  You can see that the mill is a large complex and will be an important location for operations on his layout.


The clapboard building is 30 by 12 inches with some compression to fit the layout. The full prototype size in HO is about 36 by 12 inches. There are other structures in the complex that will be nearly as big. 

The photo below shows the first batch of laser cut parts that I cut for the building while they are in the glue up. Marty will install the windows and roofs. There are several other big buildings in the paper mill complex.


I have also been helping Doug Gurin with his layout design. He wants to have a refined drawing to show to the visitors this weekend.

 I also have a small modeling project to complete for Henry Freeman as he will be in town to operate and  pick up this model.

In between all that, I made some progress on the Pungy. I painted the hull and added stem and stem head. Next  I will install the railings and deck furniture. But that will have to wait until the weekend is over.

Pungy Fever

Replica pungy schooner in a race on the Chesapeake

The delivery of the schooner Smuggler has got me psyched to start working on other ships for the layout.  I have a list of ships that I would like to have at Aquia Landing and Burnside Wharf. They are listed below in order of the state of completion of the model.


Wish List

  1. Railroad car ferry - complete
  2. Smuggler Schooner - complete built by Brian with some help from Rob. I will rename it Miss Merritt Marie
  3. Barges- 3 including one that has masts. Paul Dolkos built one for me. Two to go.
  4. Side Paddlewheeler - I have the Mt Washington kit and need to finish it.
  5. Pungy schooner - I started work on one - see below. 
  6. Pile Driver -  I am accumulating the necessary parts. I have some of the parts already.
  7. Swift Pilot Schooner   I have a kit 1/48th Swift Pilot ship. It is a simpler schooner but the kit is plank on frame. So converting to waterline could be tricky
  8. Tug boats- 2 each - one for the railroad ferry and another along side some of the barges.
  9. Steam transport -  I see several of these in prototype photos. They are like large versions of the tugs but with at least one sail mast. 
  10. Gun boat. A smaller gunboat like the USS Couer d'Lion would be better than the Passaic. 
  11. Baltimore clipper -  I see some of them in photos of Aquia Landing.  I ordered a kit for the 1/48th scale Harvey for this. That ship was built in 1847.  That is a complex sail boat with square and fore and aft rigged sails. It would take a lot of time to build but would be a wonderful addition. 
Note the ironclad Passaic is not on the final list. It is too big for the layout. I need to think of a better way to display it short of expanding the harbor scene. Nor is the Flying Fish schooner on the final list. I bought it from a custom model builder, but they got the scale wrong. I don't think it can be salvaged or converted. If anyone needs a 1/64 schooner, let me know. 


The Pungy

The arrow points to what appears to be a pungy schooner at Aquia Landing as it has the right shape and the traditional two toned paint scheme of pink and green.


N scale Pungy

A pungy is a type of schooner that was common on the Chesapeake Bay in the mid 19th century. I built a model of one in N Scale for the Lyceum Museum in January 2016. At that time I thought it would be a good ship to model in O scale for my layout.

I based the model on a set of plans I scanned from a book on Chesapeake schooners. The one I selected was built in 1863. I enlarged  a copy of the plans and then had Staples print 3 sets of them. 




O scale hull layers
I have the drawings for laser cutting the hull from the N scale model. So I was able to scale them up and use the laser to cut parts for the basic hull using the bread and butter technique. I glued and clamped those to make the basic hull shape. Then I used my Rotex sander to get the basic shape. It took about 2 hours to cut and shape the hull.  Then it needed several coats of filler and primer. Sanding the camber on the hull top was tricky. In the future I will make laser cut parts for the camber like I used on Passaic.


Once I had the basic hull shape I laser cut the deck planking. I used the laser to engrave the planks, the joggled planks around the perimeter, and  the treenails/wooden nail plugs. By the time of the ACW, ship builders used nails and wood plugs instead of treenails. But in scale, the wood plugs almost look like treenails. They are only 0.015 inches in diameter. So the engraver could handle them and allowed me to avoid a tedious task. 

Here is a shot showing the pungy next to the Miss Merritt Marie. Although not as long, the pungy's masts are nearly as tall as the bigger schooner.  Pungies were known for fast sailing partly due to the huge sails. 

Next I need to add the low railing around the hull. Pungies did not have a large bulwark. There was also monkey rail around the cockpit area, but it was not very tall. They must have been wet sailers in a rough sea.. 


In other news, I replaced the trucks on box car 1344. It was intermittently derailing when running in a train. I suspected the cast metal trucks were the culprit. So I replaced them with the new 3D printed resin ones. We'll see if that fixed the issue.

A Forest of Masts and Stacks

 



Brion Boyles delivered the completed model of the schooner today. This model started out as the Smuggler Kit by Bluejacket Ship Crafters in Maine. The kit comes with a carved solid hull. My brother Rob cut it on his bandsaw to convert it to a waterline model.

It sat for several years as I worked on other parts of the layout. About 18 months ago, I asked Brion Boyles if he was interested in building the kit as a commission. He said yes. He worked on the kit on and off for the next 18 months. He made some modifications to make it into a cargo vice fishing schooner. I really liked how he did the sails. They are much more accurate than the other schooner model I have.  He rigged one of the booms so that it can be used to unload cargo. I need to add that cargo detail. I also need to make a name plate. I plan to name it after my granddaughter, so it will be Miss Merritt or Lady Merritt.

I would like to populate the harbor with several ships to create the forest of masts and smoke stacks you see in the prototype photos. This will include more ship models and others painted on the backdrop.

3D Printed Wooden Trucks


3D printed trucks

The expansion of the layout has resulted in a need for me to have more freight cars on the railroad. I haven't built any new cars for the layout for several years. I probably need to make some new flat cars, but I would also like to try some new styles of box cars. Regardless of what I build, I will need some new trucks. I decided to make them using my 3D printer.

I started by just drawing one quarter of the truck since it is symmetrical about the longitudinal and lateral axes. Once I had the quarter section fully fleshed out in the drawing, I used the mirror feature in Fusions 360 to complete the truck.



These trucks are designed to accept NWSL 8248-4,  O scale Wheelsets 33"/145,1/8"x1.730" shouldered axles. I have 5 sets of these on hand. Plus I have a few of my cast metal trucks that I plan to replace. I don't know if I can still get these wheelsets. If I cannot, I have a lot of Intermountain O scale wheel sets on hand. I would have to adjust the drawing to accept those wheelsets.  However, I prefer the NMSL wheelsets as they have thinner treads.


I had to design the truck in parts that must be assembled. The printed resin is too stiff to allow assembly by flexing the truck like you can do with N or HO scale plastic trucks. To ease assembly, I printed the bolster and one truck frame as single piece. Thus each truck has only 4 parts. Once the wheelsets are inserted in the holes on the truck frame, and the second side frame attached, the truck aligns itself. I apply some CAA and use a small clamp to hold the parts. While the glue is setting I insert the brake beams. On trucks without brakes, I glue those beams in place. But for trucks with brakes the beams are not glued. 


You can see how the brakes beams can pivot
I made the brake beams on pins so that they can rotate. That allows me the option to make the brakes work using my photo etched parts if desired.

I designed the bolster and brake beams to fit in slots or holes in the truck side frame. I learned that if you want to do this, you have to make the slots or holes larger than the corresponding pins by a fair amount. In this case I had to enlarge the 0.065 inch holes for the brake beams by about 25%. I had to reduce the bolster locating pin by about 50% to make them fit. I am not sure why, but holes and slots in materials print smaller than the design dimension by significant amounts. 


I was very pleasantly surprised to see how smoothly these trucks roll. They have a lot less friction than my earlier versions.  Printing 3D trucks will simplify my freight car construction as in the past it took me about 4 hours to build a set of trucks using my laser cut parts. These trucks also have more realistic detail, particularly in the journal cover area. 

This weekend I also worked on a wargame project with John Drye. I helped him build a map for a game he plans to run at Fall In 2022.  The maps depicts the area near Eindhoven and Son during the 1944 Operation Market Garden. The map is a 6' by 6' piece of felt that we painted and flocked. The graphics are designed especially for the new game called Breakthrough that Frank Chadwick is developing, and John is play testing. However, the map could be used for other game systems with a little modification. It was a fun project that came out better than we expected.

We used aerial photos as a guide but the terrain is stylized to suit the game system. I painted all of the fields, canals, and roads with spray can colors using soft masks. Then we embellished the edges of the fields with acrylic paints to show tree breaks. 

John is painting some details to help delineate the fields and roads.
