I'll do a clearance diagram for the Metroliner. The big question will
be whether we allow the club car or not. I noticed it cuts the inside
of the corners much more then the other cars. I'll do a diagram that
demonstrates both.
I've been looking at catenaries designs and I think I can make them look
right. Since the patagraph is not spring loaded we would set it to run
just below the cantenary. The two main problems with them are they take
up a lot of space on at the side of the track, probably an extra two
studs, and the corners are so sharp they will be tricky to string up
properly.

The ramps might as well have the same rules as Altenburg, since you
can't go up or down them without going through Altenburg.

Well I have to do a major redesign on the bogies for my tilting train.
As several people noticed it did a nasty upwards lunge when it hit a
switch for the first time.
As far as having a plate and a tile on top of the sleepers it depends on
how much higher this is then the rails on a switch or crossover.
However since I have to redo the bogies anyway I'll take this into account.

| Yet more rtlTrain4 info. There are effectively 4 major regions of track in the layout: The Altenburg (upper) loop; this will have clearance for a metroliner at most. 6 wide trains (possibly with small clips protruding from the sides). Clearances (...) (22 years ago, 27-Aug-02, to lugnet.org.ca.rtltoronto)
