A week or so ago I jumped in to replace a dropped-out layout at a well known Southampton exhibition with Tal coed. The Friday night saw the usual last minute check of locos and a quick wheel clean. The Roco-based diesel Acapulco (think about it) that was originally built for the Edge/book project developed that clicking sound that tells you something is going to go badly wrong. Sure enough the power went, and on turning it over, the rear gear wheel had split.
Enter the power of the internet. I mentioned this problem on the NG forum. Five days later a very nice man from N. Wales gave me a pair of replacement wheelsets. Acapulco now lives again.
Thank you Mr. Taylor.
