One of the most small yet annoying problem with model train hobby is derailments. Finding the reason can also be a time consuming and frustrating task especially when more than one section of the track encounters it. One specific cause of model train derailments are dirt and dust and cleaning tracks, engines and cars is the simplest measure to do in zeroing in on the problem. Make a number of trial runs and if all goes okay, then it was just a small thing that caused it and the it’s a lucky run for the model train aficionado.
If the model train still derail, a much relevant factor in the model train or railway arrangement could be the culprit particularly if it happens in one section and pinpointing the problem may require further meticulous investigation. Aside from the way tracks are placed, other factors to bear in mind are additional locomotives or cars, and any changes in the scenery or layout. Being broad-minded is crucial in situations like this as the part where the occurrence of the derailment may not at all times be the problem.
Make sure 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. Run the model locomotive on its own without the cars and wagons. If the derailment happens in one sector of the track, the problem could be the arrangement of the track. Level your sights down the specific track section because it could be slanted in a particular angle which is too much for your locomotive especially if the locomotive’s wheels are regular ones. The curvature of the track can also be a derailment factor.
Curved tracks are potential derailers and it is also important to consider the locomotive’s axle count as well as how many cars can be connected to the locomotive. Model locomotives with six axles usually require a curve radius of 22 degrees and going 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. Other unplanned layout flaws like bumps or dips should also be sorted as these could deliver imbalance and tilting.
If you see no problem with the track’s positioning, check the cars and wagons and thoroughly examine each one especially their couplers, axles and wheels. Make sure the couplers are not mounted 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 wheel or coupling 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 option left. Once more, always clean everything that are meant to move.
Whether the derailment is caused by a small or big issue, patience and diligence is important towards zeroing-in on it and fixing it. Being a model train hobbyist needs technical and problem solving skills and every configuration and repair accomplished is part of the satisfaction model trains bring.
