last post, track (and the related elevated track structure) is on hold until I figure out the precise electrical requirements to automate the metro trains. On the other hand, I was able to make some progress, albeit somewhat slow, on the metro station itself.
I initially planned on having five windows centered on a central lobby, but I couldn't figure out how to have the right pedestrian entrance on the ground floor; the Kato structure - that was the original inspiration (and will still likely donate some parts) - has a large entrance with stairways which I like a lot.
Ken (of the fabulous Sumida Crossing blog) left a comment (see? I read and listen to comments! At Quinntopia, we're all about listening! :-) ) that inspired me to open up the ground level some more, and be less focused on lining up windows with interiors (if you read his comment on this post, you'll see what he means).
So...here's the story....as I may have mentioned, the New Quinntopia will have an elevated, two track 'metro' line that will 'wind' its way through the city. There will be one station (there should be enough large buildings in the city so that you don't get the sense this is merely a 'loop'). I want the metro trains - each going opposite directions - to automatically stop for the station, wait a few minutes to passengers to load/unload, and then accelerate away from the station. I would also like a couple of signals to handle minimal signally duty.
Easy, right? Well, part of my problem is my interest in using newer / different technology from Europe. So after doing some initial browsing of potential solutions to how I could accomplish the above solution, I ignored all the logical and practical solutions I read (Lenz ABC, Computer Control, etc... for various reasons) and decided to try and use the signalling system from Viessmann.
So I've acquired two Viessmann 5224 Signal Control Modules and two 5228 Train Control Relays to go with them to control signals, which I've connected to small loop of track with appropriate 'gaps' and contact points to activate these relays (thus the photo at top!). But these are not enough (apparently, as I'm learning).
Its funny how wiring diagrams always make things look sooooo simple!
Here's what I think might work.
A DCC Bitswitch Basic Brake On DC Signal Generator and a DCC Bitswitch Timed Stop Bitswitch.
These are 'on order' and apparently will take some time to get to me as they are in the process of manufacturing. Which means rather that figuring out the precise electrical and wiring arrangement I need for my two track elevated line, I'll have to wait and work on other projects. Which will likely be the station and the elevated structure itself, which still has plenty of work needed. I'm looking forward to providing an update on my attempt to get some automation 'the hard way' (in retrospect, the Lenz ABC system is probably the easier and more standard way to go, but I'm too deeply invested in my own dumb solution to turn back now!) so stay tuned!
NOTE: Why I chose not to use the Lenz ABC method: they require decoders from Lenz and others that can detect the right asymmetric signal (whatever that means! People put up diagrams of an 'asymmetric symbol' which I suppose they think is helpful, but is meaningless to me!), but since I have decoders from various producers, I didn't want to start removing/reinstalling decoders if I could avoid it.
The below picture shows how everything will eventual 'line up'. The red surface areas is going to be where the station platform will be.
Kato Ginza Metro Line train will perform on the Minitrix R1 radius curves....and I don't think there will be any problems. Granted, I don't think I want to even think of going more narrow than R1, but it seems to just work on this tight radius! Whew! As you can see in the below photo, I also test to ensure that my track distance was adequate (I'm pretty much going with the 'default' different for these Minitrix curves, so I didn't anticipate any issues, but you never know!).
What has become a little bit of a mental challenge is the construction of Latveria Station. As I mentioned in my last post, the Kato 23-125 Elevated Station is too modern and also too large for what I want with Latveria station. So I'm going to be using Walthers Northern Light structure to create a brick structure/facade for the station. This is completely freelance, based on what I think an old Metro line station should look like, the closest real world example found in the real world (and the internet!) is Hackescher Markt S-Bahn Station.
Stay tuned. Perhaps next week I'll have made a decision!
