Has anyone had trouble with pulling more that 3 or 4 Amfleet cars with an AEM7? I've seen comments on various threads before saying that the locomotive was too light and compared to some of the crappy locos I've had in the past, I'd have to somewhat dis-agree however; this lightness in weight appears to be part of the apparent problem of the AEM7 not being able to pull more than 3 to 4 Amfleet cars.
I haven't had this problem that others claim to have. Part of the reason why is that (and I assume most of us here have Walthers Amfleet cars) I use conducta lube on the axles of my passenger cars.
Yesterday evening (1/24/05) I successfully ran a 6 car consist of Amfleet I's behind 1 (That's right!) 1 AEM7; number 914. Although slightly more power would be acquired to get the train up to speed and acceleration was not as fast (Which adds to prototypical operation in my book; the longer the consist the lower the acceleration rate) The train, once it got enough momentum, moved at a decent clip and my MRC DCC Throttle was set at about just under 70. I did not notice any slipping in the AEM7s performance.
Now my layout does not have grades so take that into consideration, but obviously try and keep your grades down to a max of 2%. Any steeper and you're gonna have pulling problems up grade. Going up grades you may or may not have a little slipping but I think at a max of 2%, the train should be able to manage its way up the grade.
Initial reviews of the AEM7s pulling power said that it pulled about 12 freight cars or more without much trouble. This should translate into just a little more than 8 Amfleet cars found in a "Regional" consist with 1 AEM7.
I hope you will take my suggestion and experience into consideration. When using conducta lube on your axles you'll also notcie that the cars will roll allot more freely.
Just thought I'd share this with you all. Please let me know if this worked out for you or not.
