Locomotives & rolling stock for 15" radius

[Conrail Quality]

The layout is an L Loop with many drop off points. I just like to run the trains around - drop off & pickup - then run around some more. Thanks for the specific suggestions - especially the AEM-7.

Although an AEM7 may negotiate 15" I doubt amfleets, especially with close couplings will.

Just because Amtrak doesn't run them in freight service doesn't mean that they're not capable of it. In fact, the Swedish RC-4, which the AEM-7 is just a variation of, regularly does so.

So an AEM-7 in freight(or switching) service is entirely plausible.
