Quite some time ago there was a lot of enthusiasm for an O-Scale version of Amtrak’s ACS64 “City Sprinter,” but it seems that’s not going to happen.  I personally have close to zero familiarity with 3D printing, but I notice that there are several vector files out there of this engine, mostly for video, and some seem to imply you could do a 3D print using the file.  In terms of scratchbuiliding, there is not really a lot of exterior detailing to worry about, but how to make the complex curves in the two ends baffles me.  Could you 3D print just the ends and then scratchbuild the rest?  I would really like to hear other people’s thoughts on the practicality of this.

Perhaps we could make this a cooperative effort.  I would gladly design the decals, which can be laser-printed at Staples for about $4 a sheet.

On G scale train forum we build some engines. Rbrown has made some tough curves on his builds of the E series EMDs. (EMCs?)

I don't think I can do a direct link here to another forum because of the rules?



He makes molds and pours resin in.

I make mostly G scale Modern diesels with angled edges. I did make a fuel tank and just bent sheet plastic around the ends.

I like the idea of you making the engine from scratch. I don't know your skill or interest level or commitment to do this. It can be frustrating the first time. It ain't cheap either.

You have to factor in all the parts like trucks, motors, and electronics.
