Model Railroad Layout Design Special Interest Group

This discussion forum is for members and friends of the model railroad Layout Design SIG. Membership in the Layout Design SIG is encouraged, but not required.

Model railroaders, model train enthusiasts, and everyone who loves model railroading: we welcome discussion on all aspects of model railroad layout design, construction, and operation in this group!

Commercially-oriented posts are permitted on this list in moderation as long as the poster also participates in other discussions and avoids "hawking their wares" in most discussion threads. Commercial posts that masquerade as non-commercial posts are not wanted and will be grounds for being put on moderated status.

SIG membership includes 4 issues of the Model Railroad Layout Design Journal, and access to SIG events. See the SIG's membership page for full details.

Re: Liftup as entrance to train room I'm thinking about the ergonomics of one of these setups. You walk up to a doorway where one of these contraptions is installed. You lift, pull or push Posted - Tue Feb 14, 2012 12:57 pm	John Purbrick j_purbrick Offline Send Email

Re: Liftup as entrance to train room Carsten, I would add a counter weighting system to prevent damage if the bridge were dropped during a lift. This could be in the form of cable / pulley / Posted - Mon Feb 13, 2012 5:20 pm	Matt Goodman goodman312 Offline Send Email
