Radius vs. 26.4m cars

The shipment had a circle of large radius K-track which I'm planning to use in the helix for the Murrbahn project. I had some concerns about clearance in the helix with long passenger cars, but as we can see this will work just fine, even for exact 1:87 scale cars. The cars shown in the photo are 1:93 scale length-reduced. The double track is 55.3cm and 61.8cm radius respectively.

I also got some curves at 90cm radius as used with the large radius Marklin turnouts. The cars look really nice with this large radius. I originally planned to use 90cm as the minimum radius on visible track when planning the Murrbahn project. Even though the room is quite spacious, doing so has been challenging. Since the crew is on the inside of most curves, I can go a bit tighter while still mostly maintain this nice look. We'll see how this will all play out once I get to that stage.

Meanwhile these cars are safely packed away since they look terrible on the tight radiuses used on the Welztalbahn.

Untergroeningen: Module Kits

The table saw got a workout today. I cut the necessary pieces to build the frames for the Untergroeningen module set. Those modules are sized and shaped to fit with the the future Murrbahn project, but for now I'm planning to attach the module to my existing Welztalbahn layout.

Even though this is a rather low-end table saw, the cuts are much more accurate than with the jig saw, or portable circular saw. The frame and cross ties will be built from 3/4" plywood. Admittedly that's overkill and heavier than desired. However, I hope that the modules will be more dimensionally stable.

All pieces cut and arranged.

The angled segment will take some effort to get right.

Dave Parks' Cumberland West - Back at Williams Street

I'm back at Williams Street Yard. This time I was prepared. I knew what I was getting myself into. I had experienced tower operators at Virginia Street and Viaduct. I had most cars in the yard identified with their respective car cards. When the session started, I was ready to go. I made the moves I had planned for BO11, the train that started my slide downhill the last time.

Only that this time BO11 didn't arrive at Williams Street until almost the very end of the session. I even got to service BO29, the mail train. The afternoon session today apparently had run very slowly and everybody was well behind schedule.

BO29 normally gets switched on the West-bound main. We tried it on the freight siding instead, which worked well and opens the possibility for additional switching moves the B&O did to this train in 1953 at Williams Street, while at the same time not blocking the main tracks. The photo below has the Western Maryland Ridgley Yard on the right, the River Interchange track in the middle, and Williams Street Yard up on the embankment on the left. BO29 is the train with lots of express cars and the single passenger car. The Virginia Street Tower operator can be seen in the rear.

Here's BO29 after it has left Cumberland, climbing the grade from Piedmont to Oakland.

When BO11 finally arrived, it had only one car to set out and 5 cars to pick up. I switched the train with one switcher engine in less than 10 minutes, while keeping both the freight track, and the eastbound main open. The mental preparation had paid off.

End of the session. Time for a visit to the local bar.

First Sunday of Advent


Niederegger Marzipan is hands-down the best marzipan on the planet. It's no surprise that in early December there are lots of freight trains bringing the good stuff everywhere. The Marzibahn trains of course get priority over any other traffic.

There's even a video.

Saturday Evening Entertainment

On the living room couch tonight, with a glass of wine, reading Le Train, a model railroad magazine from France my wife picked up for me when she was in Europe a few weeks ago. It's a lot of work to get more than the high points out of the articles. My not-even-close-to-conversational French is hardly tuned for the specialized words and phrases used in e.g. an article about the history of the rail line crossing the Pyrenees, or the last rail-based freight services in central France. Nevertheless, an interesting exercise.

Silicon Valley Lines November Ops

We now have a nice big sign for the sidewalk. That should make it more obvious when the club is open.

Since I took the conductor role for a visitor engineer at tonight's operations session, I had some time to take photos. Below is a selection.

A Moment of Sunshine

Heavy rain. Thunderstorms in the morning. Even some hail. Today was really wet. Nevertheless, when I walked back from lunch there was an opportunity for the sun to peek through the clouds, and produce this awesome double rainbow

Something is different in the lobby today.

Good Morning

Riding the bike to the bus stop. It's cold, but really nice outside.

Digitizing Roco 43012 - Lights Almost Done

The red tail lights are micro LEDs mounted in the shell. There will also be a cab light, so I need a way to route power to all these LEDs and keep the arrangement pluggable. Here's my solution: a header soldered to the decoder "breakout board" and a perf board fragment with resistors to be kept with the shell. The "pins" are wire cut offs from resistor installs in other projects. Never throw anything away ....

Here's a side-view with the cab light LED installed, and tail lights wired. The cab LED reaches too far into the cab, and is visible from the outside. I'll try to pull it back a little bit and also limit light leakage into the machine room.

I might have to redo the breakout board, since I did a fairly poor soldering job on that, but for now let's see how this pans out.

Here's a short video of 601 001 demonstrating the light effects. I still have not closed the chassis and engine roof yet.

No work today

The shops are empty, an appropriate picture for how I didn't get much done today.
