Well, this way it gets more views, so even though misplaced, all is good.
I don't have a big enough layout to do serious "how many cars" tests. The scale Berks can easily pull any reasonable train I want - maybe 14 cars max, so the locomotive is not sniffing at a caboose. We 2-railers do not deal with traction tires, so driver slip is the way we tell the limit is reached. Never add so much weight that a model stalls before it slips - that practically guarantees motor burnout.
One of my best pullers is an 81" drivered Atlantic. One side is cast iron, the other side has insulated tires made from iron pipe. There is something about iron that grabs the rails and won't let go.
