Dad's train

A nice sunny Thursday evening gave me the chance to take out the newly named locomotive "Brian" and give it a run on the club track. Initially, all went well. But after three circuits, the loco stopped, making a grinding noise. Investigation showed the gears had eaten themselves. This wasn't good. However, to compound matters, the reason this happened is, because I am STUPID. Talking to Boot Lane, it seems there is a little bottle of oil in the package, which I seem to have lost. In the instructions, which I didn't read properly, is a note that the gears MUST be lightly oiled. Something I didn't do. They have kindly provided me with replacement gears, and oil, which I have been sternly told, should be used this time!
