Finding The Cause Of Model Train Derailment
Model train derailments are one of those tiny problems that can turn out to be very irritating. Figuring out the chief source of the derailment can also consume a lot of time and attempt particularly if it turns out on more than one track section. Model train derailments can be caused by dusts and dirt and cleaning tracks, engines and cars is the first step to perform some trial and error. After cleaning what needs to be cleaned, run your model train again and if the derailment doesn’t happen to any further extent, then cleaning did the job and you don’t have to worry about it anymore.
If derailment still happens, though, there is perhaps a much deeper cause particularly if it happens in one section and pinpointing the problem may need a more careful investigation. Aside from the way tracks are positioned, other factors to take into account 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 section where the occurrence of the derailment may not always be the problem.
Ensure that no small or big piece of sceneries are obstructing the tracks. 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 cause derailments in some cases. Disconnect all cars and wagons and just run the model locomotive by itself. If the derailment occurs in a particular track section, the problem could be the arrangement of the track. Level your sights down the specific track section given that it could be slanted in a particular angle which your locomotive can’t handle especially if the locomotive’s wheels are regular ones. Another factor that could contribute to derailment is if the track is incompatibly curved for the model locomotive.
Curved tracks are potential derailers 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. usually require a curve radius of 22 degrees and going lower would most likely derail the model train. How many cars can be connected should also be considered since centripetal force and inertia could play a role in derailment especially in tight turns at fast speeds. Also check for bumps and dips as these could cause tilts and jumps.
If the positioning of track sections have no problems, check the cars and wagons and thoroughly examine each one 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 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 the problem with couplings and wheels keeps coming back, it might be time to replace them with new ones. Again, always clean wheels and tracks.
Whether the derailment is caused by a small or big issue, patience and diligence is essential towards zeroing-in on it and fixing it. Technical and problem solving skills are just some qualities needed for a model train hobbyist and every configuration and repair done is just one of the various satisfactions model train hobby brings.
