    Re: First draft of the Lego-Modular Train layout standards posted.. —Robert Green
   Is there going to be a standard size car/rolling stock standard? i.e.,clearance on all tracks for something 8x44x14 (or whatever) I would think that this would be just as important as standard track interfaces and such, as this is going to be the (...)

   (...) 8x44 but I am not sure about the height. John Kelly? Note that 8x44 allows 7xM and 6xN (where N>M>44) due to curve effects, although I am not quite sure what the values of M and N are. That's why I personally am pleased to see layouts (...) (25 years ago, 30-Mar-00, to lugnet.trains, lugnet.trains.org)

   I'm not sure that we've really set a hard top yet. By guess is that 14 will be probably the high end, mostly because the tunnels start to look really silly if they need to let through cars that are taller than that. A lot of that will depend on how (...) (25 years ago, 31-Mar-00, to lugnet.trains, lugnet.trains.org)

   I knew that there was something I forgot to include! I think 16 was what we mentioned for tunnel clearances. I LOVED Brian Williams' suggestion of having the entrance to the tunnel removable so that a smaller or larger "mouth" could be added to look (...)

        Re: First draft of the Lego-Modular Train layout standards posted.. —Larry Pieniazek
   (...) Good point. Perhaps instead of setting a length standard (although that is useful when calculating siding capacity) the standard should speak to the envelope of clearance that must be provided. (there must be 4 studs clearance from the edge of (...) (25 years ago, 31-Mar-00, to lugnet.trains, lugnet.trains.org)

   (...) Hmm, interesting, can one come up with a single car? One thing I immediately wondered is if the clearance specs define a maximum distance between wheelsets (actually between truck pin) and a maximum extension beyond this point, would you get (...)

   (...) Sure - since the specs are being set, a ClearanceCar can be defined. Anyone building a layout that doesn't allow it to clear gets a wedgie ;-) All you need are LWH, and pivot point distances from the ends for the center of the trucks, and each (...)
