In a previous installment I mentioned that, among other problems I had a defective turnout. The replacement turnout arrived this week and was duly fitted. Since I had two spare underfloor motors, I decided to replace the surface mounted motor with an underfloor one which this turnout originally had and reserve the surface one as a spare. It was wired up and worked, albeit the wrong way round. However I am not going to bother about this for the time being. Since I had fiddled around with the CVs of some vehicles, one change being leaving them for DCC operation only, I thought I would try a couple out at low speeds, namely my class 150 and 108 DMUs . First of all I did a conscientious cleaning of the track with IPA and threw a couple of once white then black cloths away. The 150 performed very well at speed levels 1 to 5/6, whereas the 108 wouldn't run at speed level 1. I then gave the 150 (power car only, without trailer) a run at higher speed levels but at speed level 22 it was going so fast that I feared it might fly right off the board so I ended the experiment. At least, today's experience seems to show that I am finally moving towards having a usable layout. There is still a lot of work to be done because (among many other things) the 150 still derails at a particular place when the power car is going forwards in one direction. At one place yet to be located two wheels of the rear bogie leave the track and when the unit reaches the next turnout it derails. This does not happen when running in reverse or in the opposite direction. Anyway within a month I have grandchildren here and something has to work.
