i too have this problem with the Dapol o gauge terrier ie suddenly stops but a few seconds later starts again and so on in either direction, i have two of these locos and the problem persists with both of them ( maybe i am just unlucky) i have sent one of them back to the suppliers for them hopefully to rectify the problem and it looks like i will have to do the same with the other one unless anybody out there has any suggestions, it is such a shame as for the price they are really nice looking locos but i am very dissapointed with the performance
