My view is simplistic in the extreme -
1. The largest curves you can accommodate.
2. The biggest power supply you can afford - within reason. To my knowledge, no wildlife in MY backyard has ever been fried by electrocution via the tracks, else we'd be seeing the ground under transmission lines littered with corpses
Your little Bachmann unit will happily run one small loco with a couple or three cars around a small track - a larger track needs more oomph from the power unit to drive the loco - the track itself is resistant, remember.
I agree that most people over here don't run four-loco lashups with a hundred cars, but you can bet that those who do have the necessary electricals well sorted out.
