How To Locate The Source Of Model Train Derailment
Model train derailments are one of those minor problems that can become very irritating. Figuring out the main source of the derailment can also be a time consuming and frustrating task particularly when more than one section of the track encounters it. Dirt or dusts is one factor that can cause derailments and cleaning tracks, engines and cars is the first step to do some trial and error. When the derailment stops after cleaning, then cleaning did the job and you don’t have to worry about it any longer.
If the derailment goes on, there is perhaps a much deeper cause particularly if it happens in one section and pinpointing the problem may require further careful 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 area where the derailment occurs may not at all times be the problem.
Any obstruction in the tracks could show the way to derailment or blockage so make sure sceneries are not lying on any part of the track. Track nails and joints should also be inspected meticulously. 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 trigger derailments in some cases. Disconnect all cars and wagons and just run the model locomotive by itself. If the locomotive derails in a particular track section, the problem could be the positioning of the track. Meticulously look at or measure the track’s degree angle because the angle could be in a slant which your locomotive can’t handle especially if its wheels are not 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 number of axles in the model locomotive as well as the number of cars to your model train extension. Model locomotives with six axles usually require a curve radius of 22 degrees and anything much curvier 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 play a role in derailment specially when the model train is going fast on tight turns. Other unplanned layout flaws like bumps or dips should also be sorted as these could cause tilts and jumps.
If the positioning of track sections have no problems, each cars and wagons should be checked thoroughly especially their couplers, axles and wheels. Couplers should be mounted properly and should not be too low 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 wheel or coupling that is loose or tight, try to re-mount them if possible. If re-mounting doesn’t solve the problem, it might be time to replace them with new ones. Once more, never forget to clean all wheel.
Whether the derailment is caused by a small or big issue, it is important to be patient and diligent towards finding it and getting it fixed. Being a model train enthusiast requires technical and problem solving skills and every configuration and repair done is just one of the numerous satisfactions model train hobby brings.
