Ben, with your rig, how does the 8866 PF Train motor compare with the 10153
motor, for various masses of loco (say no-load, kids’ train load and AFOL train
load)?
I’ve tested the Emerald Night carriage with an 8866 motor and found that the
gearing was too high to go with a medium motor in the cab (substituted for the
usual XL motor in an attempt to get more speed, though it didn’t work).
Then I ran just the carriage with two 8866 motors, including the battery and
receiver. On flexi-track, speed settings less than 3 wouldn’t move it, speed 3
was OK and speed more than 3 derailed :-(
Then I compared pairs of 10153 and 8866 motors in a heavier 8x64 carriage, using
the PF rechargeable battery and IR receiver to control it. I found that with
10153 motors speed setting 4 was good to go all the way round my looped-eight
layout (with 1 in 30 maximum slope, up and down) (meaning that it was good to
leave it running at a show so I can talk to the public) but that speed setting 5
was needed to get the 8866 motors up the slope and was too fast for the descent
(meaning I couldn’t leave it running at a show).
Pulling another two 8x64 carriages, speed setting 4 was still good for the 10153
motors but with 8866 motors even top speed struggled on the up hill section,
cutting out the rechargeable battery 3 times, though it got there eventually.
It also caused overspeed on the descent and derailed!
Have you or others found the 8866 motor over-gearing problem?
It’s quite serious if the motor designed for the job is not right. The future
of PF trains could be at risk. I would like to recommend a redesign with lower
gearing to TLG. The 8866 motor should be made to follow the torque curve of the
10153 9V train motor, so that it is a drop-in replacement.

| Hello after a long time! I played around somewhat with the different train systems. The result is displayed in this table: (URL) And probably more interesting as a video: (URL) Pulling power of different train systems at YouTube> The used test rig (...)
