How accurate are the drawings on nycsubway.org?


Recommended Posts

Hi all,

 

I'm trying to get into scratch-building HO models of subway rolling stock and locomotives. How close to accurate are the drawings on nycsubway.org? I like to model the things on the computer in 3D to figure out any construction problems first. Here's a picture of what I have so far based on the drawings of the 45-ton switcher at http://www.nycsubway.org/cars/locomotives.html. It looks pretty accurate so far, though I'm not done. I still have to carve out the steps, the windows, and some more rails and details.

 

I've tried making one of the trailer flat cars, but I didn't follow the few drawings on nycsubway.org, and I think the dimensions turned out okay. Are the new flat cars the same as the old ones, or are they all basically all different? Here are my previous attempts at the flat cars: http://www.amrline.com/showthread.php/22187-NYCTA-Trailer-Flat-Car-Take-2 and http://www.amrline.com/showthread.php/21585-New-York-Subway-Flat-Cars.

 

Here's the computer model of the 45-ton switcher that the HO scale model will be based on.

Well considering I made this train in OpenBVE,

 

The dimensions are accurate as per data sheet, however some measurments take some guessing and calculations (Cab width, height,etc..)

I tried messing around the the "Match Photo" feature in Sketchup, and I found that the drawings of the 45-ton switcher are very accurate, but the drawings of the trailer flat cars may or may not be. I guessed that the ones I am modeling were the same length as an R-17. So, I lined up my locomotive model in a picture with both the loco and and flat car, tried the measurement, and got about 51.5', which to me is close enough.

 

In case anyone was curious. :P

That's cool, thanks for the info. Ours look pretty similar. I've got a nice set of jigs together for making the hand rails and updated the progress in my thread on AMR Line.

 

That was you?

oh wow I was very impressed with the scratchbuild.

Thanks, Mouse. I'm kind of a perfectionist, and I also don't have experience scratch building, so I end up doing things three or four times until I find a way that looks good, that seems sturdy, and that I can repeat. Which is why it takes such a long time for me to do anything. My goal with this is to make a mold and make resin copies so I can make a bunch for work trains, plus for the experience.
