Model train derailments are one of those small problems that can turn out to be very irritating. Pinpointing what’s causing the derailment can also be a time consuming and frustrating job especially when more than one sector of the track encounters it. Dirt or dusts is one factor that can cause derailments and cleaning tracks, engines and cars is one easy way to resolve derailment issues through elimination process. Do several trial runs and if all goes fine, then it was just a small thing that caused it and the it’s a lucky run for the model train enthusiast.
If derailment still happens, though, a much significant factor in the model train or railway arrangement could be the culprit especially if it happens in one portion and pinpointing the problem may need a more meticulous investigation. Aside from the way tracks are positioned, other factors to think about are additional locomotives or cars, and any changes in the scenery or layout. You have to be open-minded to be able to consider all possibilities as the spot where the derailment occurs may not always be the problem.
Ensure that no small or big piece of sceneries are obstructing the tracks. Joints and nails of the tracks should also be carefully inspected. Nail heads should be embedded all the way in the railway’s platform and they should not go through the track holes.
The cars and wagons that trail the locomotive can also cause derailments in some cases. Determining this would also call for elimination process so you have to disconnect the cars and wagons and let the model locomotive run solo. If the derailment happens in one section of the track, then the track’s positioning or alignment might be the culprit. Carefully look at or measure the track’s degree angle seeing as the track could be in a slant which is too much for your locomotive especially if the locomotive’s wheels are non-magnetized. If that particular track is curved, it could also contribute to model train derailment.
Tracks that have tight curves will potentially cause derailment and it is also important to consider the number of axles in the model locomotive 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 below that would most likely cause derailment at every pass. 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 there’s no problem with the position of the tracks, 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 wheels should also be properly set according to the track’s width. If there is one or several coupling or wheel that is loose or tight, re-mounting them maybe a care-free solution. If derailment still occurs after re-mounting, replacing them is the only alternative left. Once more, never forget to clean each wheel.
Whether the problem with the derailment has to do with small or big factors, patience and diligence is important towards determining it and getting it fixed. Being a model train aficionado needs technical and problem solving skills and every configuration and repair done is part of the satisfaction model trains bring.
