My son was given a Lima Class 20 loco which must be 20 - 25 years old.
Tried it on the test track .... no movement just a loud hum and a rattle.
How to remove the shell ? Eventually noticde one of the buffers looked as it was pulled out so tried the others and presto off came the shell.
The reason for no movement was that the drive shaft had become displaced. Soon got that sorted but then noticed the drive wheels looked like they needed a good clean.
I know Hornby loco's sometimes had / have rubber traction wheels but did Lima ? Looked like a grove in the wheel was to accept the tyre but do the replacements come separately or do I need to replace the whole axle ?
The design of the power train looks a little poor to me. No disrespect to the original design team but the Class 20 looks a bit like they ran out of time when they came to the design of the cab and simply bolted an old shunter cab on the front but back to front.
