One of the most small yet irritating problem with model train hobby is derailments. Finding the cause of it can also prove challenging and frustrating if quite a few sections of the tracks get affected. Model train derailments can be caused by dusts and dirt and cleaning tracks, engines and cars is the first move to perform some trial and error. When the derailment stops after cleaning, then it was just a small thing that caused it and the it’s a lucky run for the model train enthusiast.
If the model train still derail, there is possibly a much deeper cause mainly if it happens in one portion and pinpointing the problem may entail further meticulous investigation. Aside from the arrangement and positioning of the tracks, other factors to bear in mind are the sceneries and the locomotives and cars. You have to be open-minded to be able to consider all possibilities as the section where the derailment occurs may not always be the source of the problem.
Any obstruction in the tracks could show the way to derailment or stoppage so make sure sceneries are not lying on any section of the track. You should also inspect track joints and nails carefully. Nails should have a packed fit on where they sit and loose ones should be examined immediately and tweaked if needed.
The cars and wagons that trail the locomotive can also cause derailments in some cases. Disconnect all cars and wagons and just run the model locomotive by itself. If the locomotive gets derailed in a particular track section, then the track’s positioning or alignment might be the culprit. Level your sights along the specific track section given that it could be tilted in a certain angle which is too much for your locomotive especially if its wheels are non-magnetized. The curvature of the track can also be a derailment factor.
Tracks that have tight curves will potentially cause derailment and it is also important to consider the locomotive’s axle count and also the number of cars to your model train extension. Model locomotives with six axles usually require a curve radius of 22 degrees and anything lower would most likely derail the model train. The number of extension cars and cabs should also be considered since centripetal force and inertia could be factors in derailment specially when the model train is going fast on tight turns. Dips and bumps should also be checked as these could tilt or jump the train.
If you see no problem with the track’s positioning, each cars and wagons should be checked thoroughly especially their couplers, axles and wheels. Low-mounted couplers should be elevated and all wheels should easily turn. The width of the track should also determine the width of the wheels. If there is one or several coupling or wheel that is loose or tight, the basic solution is to re-mount them. If derailment still occurs after re-mounting, replacing them is the only alternative left. Again, never forget to clean every wheel.
Whether the problem with the derailment has to do with small or big factors, patience and diligence is important towards zeroing-in on it and getting it fixed. Technical and problem solving skills are just some qualities required for a model train hobbyist and every customisation and repair accomplished is just one of the many satisfactions model train hobby brings.
