Forgive the fact that I will not be too astute in describing the issue. Our train club recently purchased a White Pass Annie. We have limited the consist to four Bachmann passenger cars so I don't feel that the locomotive is being overtaxed. Yesterday after it had been running for about twenty minutes on a warm sunny day, we noticed a noise which we think may be caused by the drive wheels (or one of them) being out of phase. It is a "thump" noise that arises only when the locomotive is running forward. If we run in reverse the noise seems to go away. We have been keen to lubricate the locomotive regularly and can't find evidence of dirt or other debris. Our inspection revealed that the pair of drivers under the cab seem to have a bit of play in them, far more that the feel of the forward drivers.
Does anyone have a similar experience and what can be done to correct the problem. Thanks.
