Urban Station
New Kato Catenary Sets
04 May 2012 23:13 Filed in: Structures,Review
Kato recently introduced several new sets of model catenary poles for its N-scale Unitrack. Like the earlier ones, these are non-functional plastic castings that snap together, and clip to bases that align them with the track. Two of the new contributions stand out: one is a set of four-track catenary supports, and the other is a set of platform detail parts, including catenary, for a Shinkansen station. I’ve updated my Kato Catenary page with new photos and details, but I wanted to say more about the interesting ones here.

Plans for an Arduino-based Tram Controller
Today I want to mention one of my other projects: the control system for the Tram line of the Urban Station scene. Now this is a simple, short, out-and-back line, which exists mainly to give me an excuse to buy some of the Tōkyū Setagaya line light-rail vehicles (see the Tram section of my Roster) and to experiment with Tomix’s mini-rail Finetrack. So far I’ve run this manually, with a Kato powerpack. But I want to automate it, since the trams are just supposed to be background activity to make the station look busier, as I concentrate on running my commuter and express EMUs and freight trains.
The problem I had was that I wanted to replicate a two-track line with unidirectional running, and a single track station at each end that let the trains switch between the two tracks, and I wanted to do this with more than one tram running at a time. The track I’m using has slip switches, which allow a train to run through them even with the switch set against it. This lets me leave the switch in one position, and have a train enter the end station from one track and leave on the other, without any switch-control needed. Read More...

Viaduct Station Extensions
The elevated station was originally intended to be made entirely using Kato’s Viaduct Station (23-230) and Viaduct Platform Extension Set (23-232) sets. The problem was that at the ends, the flat supports I was using to hold it up would come down into the space needed by the subway train, and raising it up another quarter inch wasn’t very desirable. Without those supports, the plastic tended to sag where it was unsupported. Read More...
Upper Level Return Tracks
19 April 2010 00:26 Filed in: Construction,Design
I took a short break from working on the elevated station to assemble the upper level of the unsceniced end, as well as a couple of lower-level (i.e., subway or “water” level) sections of plywood adjacent to and extending the Urban Station and Riverside Station scenes. I also decided how to end the Urban Station scene: on the extension will be a small canal, with the “commercial avenue” continuing over it on a bridge. This is based (very roughly) on the Yoko-jikkengawa river. Read More...
A Tram Line for Sumida Crossing
The latest change to the evolving design of the Urban Station scene is the addition of a light rail line, or tram as they’re commonly called in Japan. This is a simple half-loop of double-track, with stub terminals at each end, and one mid-route station. The line begins immediately under the main station, heads towards the river and curves across the “commercial avenue” that parallels the station, then runs along behind the row of buildings until it reaches the far end of the scene, away from the river. This use of a private right-of-way running behind buildings is typical of the two remaining tram lines in Tōkyō. Read More...
March 2010 Status - An Urban Station, almost
Another month, and it seems like there isn’t much to show for it. That’s somewhat deceptive as many things have been accomplished, but nothing has been finished, and that makes it seem like less was done. I’ve covered most of this already, so I’ll quickly summarize the work. Read More...
Incremental Changes

Work on the layout continues, but without much visible to show for it. Mostly it’s been more of things I’ve already done: building the second set of supports for the other half of the elevated station, more roadbed painting, and preparing the fascia for the Riverside Station scene (complete with cut-out windows to view the subway).

Raising Steel
07 March 2010 19:40 Filed in: Construction
Metal isn’t a construction material usually associated with model railroad layouts. But for some applications, the strength it provides is worth the extra effort to work with it. For my elevated station, I wanted a strong yet “prototypical” support structure, and couldn’t use the pre-made viaduct supports normally used, as I needed the station higher to clear the subway tracks. My solution was a sparse set of columns, intended to look like the cylindrical concrete columns used in some large buildings. Read More...
January 2010 Status - Planning the Upper Level
30 January 2010 22:34 Filed in: Electrical,Monthly Status
This month was spent thinking about the track that will go on the upper (ground) level, above the subway. I never actually did finish wiring up the subway loop (although I can run trains on it using DC, they get a bit slow on the opposite side of the loop from the powerpack; rail is a poor conductor of electricity).
