Jason,

I checked with my laser cutter friend. He is busy with structures. He
said if you simply want to cut the four sides of a locomotive cab for a one
time project, it would be less trouble to do it manually with a knife.

He would have to take your scale drawings and convent them to AutoCad and
then set up his laser cutter to do it. He couldn't give a price unless he
had the drawings, but it would probably be in the $100.00 range.
