OK, I have heard many requests for a new F40 and when my new BL-2 Mechanism showed up I just had to try something Check out the pictures Now this project has little interest for me as it far too modern. I will be using this chassis under an F9. However I just had to plant the seed for someone to do this up right. You would end up with an F40 that could pull stumps and run incredibly slow. For all the guys crying about this locomotive, here it is. You don't even need to mill the frame to put a decoder in. This has got to be the easiest locomotive project I have run across.
