Roundhouse shell

The roundhouse shell is complete.

Some work benches and tool cabinets are in place
So far, so good. After looking at the photos for a while, I decided that I'm not happy with the look of the exposed plastic. Never would have thought that I'd get this anal about the inside of a building that will be located towards the back of the layout room.

There needs to be an easy way to simulate a somewhat dirty off-white brick wall for the inside of the roundhouse. This would have been easier with the walls off, but I figured it won't bug me that much. MEEEEK! ... Wrong.

At a minimum, I will just paint the inside red walls with some off-white color and "dirty them up" during installation of the roundhouse tracks. No brick texture, but better than these red plastic panels.

What are options to get some texture on these walls? It needs to be easy to cut and install, and should take paint well (if not in the right color already). Some kind of wall paper, maybe?

Roundhouse progress

The roundhouse is starting to come together

With the window frames in, the mortar doesn't look quite as bad anymore

The inside is getting some furniture, including an oven.
Inbetween tasks and work, I'm slowly making progress on the roundhouse. I contemplated (and tried using posterboard) to give the inside walls a more finished look, but then decided against it. It's a lot of work for minimal gain. Maybe I just paint the walls using a dirty off-white color. The inside of the roundhouse will have lights, so I'm hoping that will be sufficiently effective.

Emsingen Ef

Testing placement of Emsingen Ef
I always had a weak spot for this Faller "Reiterstellwerk" model. It's not exactly one of the most authentic towers out there, nor does it fit perfectly at this location, but I couldn't resist when I saw it at a dealer's table at Eurowest yesterday. This tower will be called "Emsingen Ef" for Emsingen Sued, Fahrdienstleiter, i.e. it's located at the south end of the station and the dispatcher for Emsingen works in this building.

The levers ("Hebelbank") are in the bridge part of the tower, so this couldn't be a purely mechanical tower. There's not enough space underneath the floor to run the actuator wires. However, it's feasible as an electro-mechanical tower, where the levers electrically actuate signal and switch machines in the basement on the right, which then move signals and throw turnouts.
I'll place a small tower ("Emsingen En") on the north side of the station to guard the railroad crossing and operate nearby turnouts and northbound signals. Admittedly, two towers is somewhat overkill for a station the size of Emsingen, but there does need to be at least an attendant shed at the crossing to ensure vehicle traffic is safely off the tracks.

To properly set Emsingen Ef in place, I need to level the ground and cover up the semaphore machines, as well as add some lights at least to the bridge part of the building. I hope illumination will show off the Hebelbank, especially at night.

Aside from the tower, I also bought background buildings for Emsingen, and some additional detailing for Emsingen station.

Patina




A new project. I might have overdone the mortar a bit, but will tone it down a bit in the final stages of assembly. Really looking forward to building this model.

That pesky curved turnout

I mentioned before that the curved turnout on the ramp from staging didn't want to play ball with BR24. Today I ran that locomotive over the spot where it got stuck consistently two weeks ...uh, a month ago, and sure enough, just like last year, no problems anymore.

However, since BR24 has the pickup shoe below the locomotive, and the loco frame is quite a bit more open than the tender of BR50, I could actually observe what the pickup show is doing as it glides across the turnout. At one point, right above the pivot of the turnout points, the pickup shoe drops and then gets lifted up again.

Even closer observation showed, that there is potential for the pickup shoe to slip off the raised point contact in the area, and then get caught in the next middle contact.



To work around this problem, I super-glued a small piece of styrene into the turnout that should keep the pickup shoe out of the "hole" and in line with the top of the point contacts. The ramp from staging comes from the right.

Yes, all of staging is built with Maerklin M-track.

Emsingen Southbound Semaphores


The southbound semaphores in Emsingen now also have power. Stationary decoders are installed, and I should get around to wiring them up in the next couple days. All the JMRI routing logic is already built and ready to go.

"Paneling" ...

Panel for stub-ended staging and ramp cross-over 
... or what do you call the process of building panels?

Today I finally built the panels for controlling the turnout ladders in hidden staging, as well as the hidden cross-over on the ramp.

I didn't bother with turnout position feedback on these panels since I eventually will have a monitor on the wall that shows turnout positions, occupancy, and maybe even a live video feed of the traffic on the ramp. Also, all these turnouts are driven by solenoid motors, so there's a satisfying SMACK whenever they throw, so you know you hit the button right. I'm using push-buttons for the route selection, just like on the rest of the layout. However, the cross-over is controlled by a toggle switch. There are only two scenarios when this cross-over is used, and both require the train to be under manual control:

  • A train leaving staging, but using the inbound track of the ramp (e.g. to bypass a train that's already waiting on the outbound track.
  • A train entering the stub-ended staging tracks 5 through 8.

Panel for entering through staging from the ramp
Eventually (in the far, far future), there could be automation in staging that takes a train from the inbound (downward) track on the ramp to one of tracks 1 through 4 for storage, as well as release a train from these tracks and positions it on the outbound track of the ramp.

For now, there's manual control of trains in staging (supported by occupancy detection), as well as manual selection which track the train ends up on.

The panels are made from hardboard and are -- obviously -- very basic. However, they are relatively quick to build,  ... and throw out if needs change.

And here's an overview shot of what the Talheim operator position looks like. I intentionally split the panels for staging in two, so that they can be reached easily by the operator/dispatcher working behind the Talheim operator, as well as are within easy reach for one man operation.

Pascal's backyard bench


Pascal designed and built this bench from plywood and thin tree branches. I helped him just a little bit with drilling the holes in the plywood. He is already building his next piece of backyard furniture. Stay tuned.

Time to go home


This was a really busy week with long hours. The plane for my flight just arrived and it looks like we'll be leaving on time. I'm very much looking forward to being back home and a relaxing July 4th week.

The Kendall in the rain

View from the office. Those white specs are raindrops.

Hmmm. For some reason over the years I developed this strange fascination with rain. Must be the California sun drying out my brain. Being outside during one of yesterday's thunderstorms was quite exciting, too.

Nice job, 788

Whenever I fly with United, I enjoy listening to the communication with the air traffic controllers on channel 9.

While waiting for today's flight from San Francisco to Boston, I noticed already that the airport was very busy. Lots of planes moving about on their way to and from their parking positions.
Eventually it was our turn for departure, pushed back, and after some taxing lined up on runway 1R ready for departure.

Arrival traffic was super-busy. The controller was talking non-stop, arriving planes were talking over each other…

"One after the other, please" - SFO Tower

Every 45 seconds or so a plane was announcing visual of the bridge and the runway, indicating they are in final approach. Both arrival runways in operation.
I was thinking we're going to sit here for a while, when the tower advised our pilot that there'll be an opening soon.

"United 788. I'll let you out in a little bit. No delay!" - SFO Tower

and a short time later:

"United 788. Cleared for takeoff." - SFO Tower

Immediately, the engines reved up and we started moving. … I looked out the window to the right as we crossed runways 28 and could easily make out 7 planes lined up for landing. One of them really low and obviously close to the runway.

Soon after we went airborne.

"United 788. Nice job!" - SFO Tower
I'm on my way to Boston. Again.

Fifth Operations Session on the Welztalbahn

This session ended up being split over multiple days, because of time constraints and novice operators.

My Dad and Wolfram ran trains based on a light schedule, while I dispatched, and prepped staging on the fly. This wasn't a particularly fluid session, though I think everyone got the hang of it eventually. Wolfram commented later, that he always considered a freight train as one whole, and the act of breaking it up and sorting the cars was a new concept he really enjoyed.

Dad switching in Talheim
As always I learned a few things...
  • Make the control panels less confusing.
    Mixing route control and local controlled switches on the same panel is sub-optimal. In addition many first time operators have trouble correlating the panel schematic with the tracks. Still trying to decide if this is a fundamental problem when folks are unfamiliar with a layout, or if there's anything I can do to make this easier.
    I've seen this on other layouts that use panels, too. It takes a little bit time to map lines in a diagram to tracks, but I can likely improve on the presentation of the panels. E.g. I'm not sure how far I want to go with providing feedback on the hard panels. Switch positions: Definitely... Signals: Maybe... Occupancy: I don't think so.
    A bit more signage and track names/numbers on the panels should be helpful, too.
  • Build panels for hidden staging and make occupancy feedback more fluid
    Controlling the train room computer by Remote Desktop from a laptop is sub-optimal.
  • Better seating
    At least the Emsingen panel is hard to see in it's current location while the operator is standing. An unfortunate side-effect of the Emsingen "control pit".
  • When preparing a session I need to better take into account experience level of operators
    The last few sessions I had a very experienced operator running Emsingen Yard. I ignored how steep the learning curve for this actually is. Both in terms of concepts, as well as being efficient in switching moves.
  • When preparing a session I need to better take into account what operators are interested in.
    Not everyone enjoys switching operations as much as I do, and the layout has sufficient opportunities to keep train activity up (e.g. on operator might be running 2-3 passenger trains concurrently), while another operator might be doing light switching in between those "scheduled" trains.
  • There were a few mechanical problems
    Two dead spots on the down ramp to staging, as well as the pick-up shoe of one engine (BR24) getting stuck at the top of the ramp just before the curved cross-over. I experienced the latter problem around the same time last year with BR50, but then it disappeared and I was unable to track it down completely. I suspect this is related to wood expanding/contracting as the summer season heats up. This time I have a pretty good idea about the culprit and might build something from styrene to guide the pickup shoe over the trouble spot.
Over the course of 2 evenings we ran the 5 scheduled freights, as well as a few passenger trains.

Maker Faire Redux

Remember when I wrote how Pascal was fascinated by the pinball machines of the Pacific Pinball Museum? He was totally immersed in the games, the lights, the ball, the flippers...

Today, I came home and Pascal had built his own personal arcade from shoe boxes and cardboard.

Fixing the rotating flipper on the "big" pinball machine. Pascal re-used a motor from his roller coaster for that.

The "first" pinball machine. Ingenious use of pencils as axles. They work very well, by the way.

A proud Maker!

The ball gets flipped up the ball channel with your fingers. The flippers are rotated by hand. The boxes sit on wooden blocks. Love it.
