Run your model in for half an hour in each direction at a medium speed, but also test it over the entire layout. Take it through point work and curved track, making sure there are no derailments.
Check the wheels
Clean the wheels, check the space between them and put the locomotive on a rolling road. If there are any abnormalities you will notice the model wobbling and be able to hear anything that doesn’t sound quite right.
Remove foreign particles
Layout owners with pets, this one is particularly for you! The magnets in the motor can pick up stray track pins and the wheels collect pet hair. Tweezers will fix this but if left untreated it can cause damage to your locomotives.
Once your maintenance is complete, it might be an idea to lubricate your model again. Some of the cleaning and poking around may have removed some of the oil. A drop in the indicated areas in the model’s instructions will suffice.
Get the Gear
Whilst comparatively expensive as a one-off purchase, rolling roads are invaluable to the long running of your locomotives. This one from DCC Concepts was our ‘Best in Test’ in How to build a model railway volume 2 and is available from £74.95.
