AC4460CW idle is a free online Railroad Discussion Forum and Railroad Photo Gallery for railroaders, railfans, model railroaders and anyone else who is interested in railroads. We cover a wide variety of topics, including freight trains, passenger and commuter railroads, rail news and information, tourist railroads, railway museums and railroad history.

This past Thursday was able to spend some time watching trains at Kansas City Union Station. While there AC4460CW UP 6945 stopped for a bit right in front of where I was parked. It seemed to have a lope to the idle. Is this normal for that model? Most of the locos I've heard idling had a even idle to them but this one sounded rougher.

Yes it is normal. All GE's will have a lope when they idle. Especially when you hear them at the low idle. They will be at a high idle when there is more aux power needed like when the air compressor kicks on. GE grinds their cam with quite a bit of overlap. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to - An online railroad bookstore featuring a curated selection of new and used railroad books.
