Derailments are sent to try us and boy oh boy, do they put your brain into a spin, trying to work out exactly what is causing the derailment. You can have 3 locos with 2 of them going over the track easily but the third loco derails. Go figure!

This derailment is on a new section of track that has been inserted with a new turnout . This new turnout is also in an awkward location which makes it hard to visualize the problem. The front section goes over the track but carriage derails.
I have been struggling to work out why the train derails, so I made these tools to assist me to narrow down what the trouble is. Turns out, there are a few different issues that need to be fixed.
Derailment tools I have found handy.

I have found these self made tools very helpful at checking the rail gaps. These are easily
made and assist you to check the track in a number of different way.
