I picked this Bachmann GP40 up in Alexandria yesterday. It was built as 6 wheel pickup and 4 wheel drive. I rebuilt it last night so it's 8 wheel pickup and 8 wheel drive.
Here's the project I chose to do today. Seems I have this UP dummy GP40 locomotive. I want to put it in consist behind my two SDP40F's but at 1.5 ounces it's much too light for that.
I removed the shell exposing the empty plastic frame within.
I then packed the frame with modeling clay to give the loco a weight of 5.5 ounces.
