Large Scale Trains Power Tips

Conventional track power is the choice of the majority of large scale train operators. Since most engines come ready-to-run on track power, this is reasonable. Under some conditions, the system does indeed work adequately well.

Battery powered Large Scale trains have become very popular especially in environments were track cleaning gets to be a real problem. Battery power completely avoids many of the problems that come with track power, but it introduces a different set of problems. In a sunny environment or indoors, track power works well. However in other environments, it hardly works at all, splashed grit on the rails is death to track power and wet rails oxidize much faster. Snails and slugs leave slime trails and which are good insulators and ants can leave weak acid at the tracks which is corrosive.

Digital Command Control is a system which distributes control signals to each locomotive through digital coding of a signal on the track. Power is distributed on the track as well. DCC has become popular in the smaller scales to allow independent engine control of many engines on the same track. Larger and club layouts benefit most from DCC, but any size layout can use DCC

Large Scale engines are big enough to make live steam practical. Only a small percentage of
hobbyists use live steam, but those that do are often nearly fanatical. To be bitten (or perhaps
burned) by the live steam bug seems to be a terminal condition.

If there were a "best" way to power large scale trains, then there wouldn't be any need for this page as everybody would already be doing it the best way. However, there isn't a "best" way for everybody as each method has both significant advantages and serious disadvantages. The choice is therefore a trade-off and the factors that influence that trade-off vary sharply depending on many conditions such as environment, operating practice and personal preference. Since all the the methods discussed here actually work, its the downside factors that you should pay most attention to.
