Station on a Curve

From experience all I can say is that 12 inch radius track is too tight so 24 inch would be tootight for OO. That is assuming you are using standard bogie stock.

Depends on how realistic you want it to look. Can your passengers jump a

At some tightly-curved platforms on the New York subway, they have little bridges that trundle out when the train stops. The departing train contacts rubber rollers, pushing the bridges back. (At least that's how it worked last time I was there.)

Personally, I wouldn't build a platform on anything less than a 3rd radius curve, as has already been said, clearance is a problem. If you look at
