As the title notes, I've been working for several years on designing many of the great American passenger-trains of the '30s-'50s in ten-wide (1 stud=1'; more-detailed minifig-scale). Hopefully I'll have some pics next week, as soon as I can find info about interior colors...
To put it mildly, each single car for these trains would have as many pieces as the UCS Star Destroyer and end up a little over 2' long assembled.
Currently in progress: (most of these targets were selected because Model Railroader magazine did special features on them, so I have the plans and elevations I need for all except the UP)
1951 Santa Fe Super Chief: due respect to James Mathis and LEGO, I aim to show them how this one's done! Mine may not have full handrails, but they will have interior lights...
1938 & '48 New York Central 20th Century Limited: old family business, plus '38 used most of the "standard" prewar sleeper types from the Pullman catalog.
1938 & '49 Pennsylvania RR Broadway Limited: '38 sleepers mostly same as NYC '38 Century, plus you can't really do one of these archrivals justice without the other.
1941 NYC Empire State Express: the last streamliner to enter service before WWII killed non-war production.
1947 Great Northern Empire Builder: First complete postwar US passenger-train reequipped.
1948 CB&Q/D&RGW/WP California Zephyr: Two words. Dome cars. Lots of 'em.
Union Pacific prewar City of Los Angeles/City of San Francisco: usually equipped near-identically, so what I can't reuse from the '38 NYC/PRR gigs I can leverage from one to the other.
Not passenger related but still rail: "Double Diesels"--EMD DD35/DD35A/DDA40X, ALCo C855A/B, and GE U50/U50C, same scale. The DD40, probably the biggest of these, will be ~100 studs long...
Anybody have particular requests for me to start queuing up on this? Note: As I can't get most of the bulk-parts I need through LEGO Factory or Pick-a-Brick (nor could I afford it even if they offered every different piece they make in every color), and am not now nor expected to become a Master Builder, this project is confined to CAD renderings--but I would be glad to post the completed files for perusal and critiquing once they're done.
