Why is it that I can run my Athearn engines at full speed through the entire layout, including turnouts and yards, with no derailments and my Proto 2000 and Atlas engines derail at slow and fast speeds? THe cheapest engine I own can run on code 55 rail through curves at full throttle no problem. My Proto 2000 SD7 derails going very slow. Weird.
Please discuss.
What kind of Athearn engines are you running?? Are they 6 axle trucks like your SD-7?

Thats very strange, it should be the other way around. going to fast and derail. It could be that the code 55 which is allot shorter might be letting the newer engines bottom out if you have ballast on your track. I noyiced this a few years back, the the older BB Athearns bottom of there trucks sit just a bit higher in the rails, it almost imposibble to see but it is there.
That doesn’t surprise me seeing that the Athearn units are lighter then the Atlas and Walthers engines.You see a 1/24 or 1/32 slot car weights less then a Athearn engine and will stay on the track at high speeds with normal racing abilities…
Another factor to think about is the plows on the Atlas engines might be hitting the C55 rail head…The Walthers/P2K engine truck gear cover plate has always been a tad to low.I caught this years ago when I bought my first GP18 back in the early 90s.
sounds right to me i agree with everyone
