The only reason your train stops is because the electricity stopped.
The culprit is usually dirt – somewhere. The other possibility is a short – does the grade change at that point? Rail joiners are not reliable conductors of electricity – soldering a wire joining two pieces of track (electrically) can sometimes solve these problems.
The best way to investigate track problems is to use a continuity tester – a battery, wire and light will do. The light should burn brightly when two adjoining pieces of rail are tested. Don’t forget to test each rail at each joint.
electrical problems are the most frustrating in my book.

i know that it depends on the quality of the engine, so lets assume that the quality is average

It also depends on the transformer. I just have the cheap ones that come with sets. I burned out one when the engine derailed, but kept drawing power for several hours. Another burnt out when I tried running two engines at once. But the most I had was about 20 cars.

Remember, a scale model train is a microcosm of a train and whatever scenery you have. A 10 car train can represent a 50, or more, real train.
