Hi all, I've just returned to n scale after a 30 year break from rail modelling and bought my first loco, a Lifelike BL2. I was amazed at its performance especially at slow switching speeds, so much so that I ordered another one. When I test ran the second loco, I was very disappointed. The slow speed running was uneven, and in reverse, the mechanism howled. I returned it to my supplier here in England for a refund. Did I do right or would the loco have performed better after running in for an hour or two? Any advice would be much appreciated. Jerry Stebbing.
