Power Consideration of Model Locomotives

When setting up a model railway layout you need to consider the power output of the locomotive that will be pulling the carriages. If you add too much weight then there will be very little forward motion as there is not enough power in the motor. Ideally you can do this by trial and error, but you can also read the instruction booklet for technical specifications. Model locomotives such as the Polar Express manufactured by Lionel can usually pull a very large number of carriages, however as a rule of thumb the cheaper the model locomotive the lower its max power output will be. The actual quality of the track is also important as the more resistance to forward motion there is the more power a model train will need to run. Buying a kit removes this kind of problem because at the manufacturing stage the designers make sure that enough power is incorporated.
