Barry,
4 of my Transformers were on the power station just above the 1st level of the layout, 2 of the older ZW's were under the platform with the handles left up to around 16-18 Volts. Using either the Z4K or the ZW's and starting with the handles down, some of the P3 engines had problems, and did crazy things. Leaving the ZW handles up an initiating power, the P3 engines usually ran correctly, there for because the Z4K needs to be started with the handles down to reset, which by the way I think is poor engineering on MTH's part, the P3 engines had problems on those particular tracks powered with the Z4K, the ZW left with the handles up, usually ran the P3 engines correctly in all modes. Something in some of the P3 engines, is not functioning correctly in the Conventional TR TIU mode, using the TR Z4K mode P3 engines do seem to operate correctly. When the P3 engines came out we had a similar discussion on this subject, when I said I owned no P3 engines because we had encountered some problems with them, now this gentlemen is saying something similar, only he is using the bricks to counter act the problem, instead of the ZW with handles up.
