M.S. says...As I promised here are the photos of my two favorite engines. As seen in the photos I hooked them together and they pull even better. Ive had Lionel engines for quite a while but these BEEPs are my new favorites. I plan to collect as many BEEPs as I can.

Photo shows RMT-4421 BOSTON & MAINE #1703 and RMT-4212 NY CENTRAL #5904 BEEPs double-headed on a 'hotshot' freight.
