Crikey - if I may put forth my pair of pennies, this all does seem rather alarming! Having designed a 009 layout (not yet built nor parts purchased) that I am quite proud of, reading through this thread has very nearly put me off! I had been hoping to use the Heljan locos and Peco stock to put together "yet another confounded fictional branch terminus" layout as the small gauge allows me to get more out of the little space I have. Fingers crossed, that Heljan do indeed succeed in ironing out the issues before the next batch is produced (if, that is, I've understood the musings of this thread correctly), otherwise I don't think I'll be parting with my precious Pounds - many of them, for these locos .
Back to my original plan for a terrible OO layout it may well be. Shoot.
