First, based in responses to my e-mail the other day regarding why Bachmann puts capacitors on its EASY/DCC/DC motors, I now understand. In fact, Bachmann called and indicated this was the law in both the US and Europe for the suppression of electrical interference. In any event, I now understand and know what to do. Thank you.
Here is a more challenging riddle. I have been inventorying a lot of old diesel motor power and I've put away over the years. By now you must know I have retired and am returning to my true vocation. Here is my question. Most of this power are F3s, F7s F9s etc, but predominantly “sharks.’ -- It's a freelance railroad named the Cumberland and Ohio. There are , however, two B units, that are unlike all of the others. Yet there must've been a relationship because they have been stripped and painted in our colors many years ago: DN blue and white. These B units are somewhat larger ( not much) then the F3/7s but definitely not sharks. What distinguishes them are: 1) doors at each end with porthole windows; 2) a door in the middle of the body on each side with a porthole window on the door; 3) a horizontal fan vent across the entire body -- not chickenwire-- with a gap where the middle doors appear; and 4) a large circular fan on the roof ( maybe for a steamer unit on early diesel passenger service?) Your guidance, as always, is appreciated. Thanks.

You posted this same thing in the Prototype info section and I answered it there; you've got an Alco FB-1 or FB-2.
