Hello after a long time!
I played around somewhat with the different train systems.
The result is displayed in this table:
And probably more interesting as a video:
Pulling power of different train
systems at YouTube
Only the step 4 is featured in the video.
Hope you enjoy + Leg Godt!

Very interesting experiment with plenty of variables to consider. It has my
mental wheels turning...
It would be interesting to see this done with a
“pull type spring scale” to measure the force... It would also be interesting
to adjust the mass over the drive wheels to determine the impact on gaining
traction for a specific system (given the coef. of static and dynamic
friction)...
...when I’ve met with design engineers at GE Locomotive in the past, they always
said the more weight in their deisel engines the better for pulling power. I
wonder how much that applies to the various LEGO systems? ... Hmmm... That
could be a great next experiment - to see how varying mass over driving wheels
can maximize the pulling power of an LEGO system engine....
Take care,
Ted A.
