This loco has an intermittent fault where sometimes it stops and sometimes it does not. I was too quick to rip up the track rather than test other 0-6-0 locos on the same track. I soon found out after this the loco was stuttering on other parts of the track too. Here you see a Two class 08's and a Hunslet shunter going over the same track as smooth as silk and the J94 stopping sometimes and sometimes not. Also the red light on the transformer was going dim when the loco was stuttering.
