A guy posted this on one of the Yahoo groups I belong to and I thought you all might like to enjoy it also. This is a great video of the locomotive construction process back in 1935 and shows the process from the ground up. Hope you all enjoy it as much as I did. Oh yes, I forgot to mention there is even some large scale 3-rail trackage in it.
