It's been too quiet in here lately, so I thought I'd dig something up. This one's for all the fans of the rivalry between EMD and ALCo. It's ironic that the two have been blended into one another by our guys. Check it out: (URL) is the WDM-3D class, (...) (20 years ago, 29-Jan-05, to lugnet.trains)

(...) Hi ! The devices you are referring to are RFI suppressors. They are simply little blocks of ferrite surrounding the wire to add a miniscule (a few hundred nanohenries at most) amount of inductance to the wire so high frequency doesn't get (...) (20 years ago, 27-Jan-05, to lugnet.trains, FTX)

(...) The big advantage of a OP engine is that you get good scavange air flow via the two ends of the cylinder being open at the same time. So, yes, it is in some ways more complex (timing gears between crankshafts, rather than valves), in other (...) (20 years ago, 27-Jan-05, to lugnet.trains)
