i made some pics of my parts:
from top to bottom:
-long cylinder (7.5mm), long magnet (D10mmxL7mm), overall cylinder length 8mm
-short cylinder (6.5mm), long magnet (D10mmxL7mm), overall cylinder length 8mm
-short cylinder (6.5mm), short magnet (D10mmxL6mm), overall cylinder length 7mm (these are too short to connect)
-"modern" magnet (2959c01.dat) with the holder (2607.dat) (magnet size D10mmxL7mm)
Also, the rear connector is always the same (could be subfiled)
I have more train magnets but have to dig them out...
i tested them, but i guess due to the age the older ones are weaker.

Are there any use cases where the length of the magnet makes a functional difference? Could it be could enough that the magnet (sub)part is a simple cylinder that can be scaled on the user side?

Beside the magnet lenght how about the different hooks?

I think the first 2 cases (8mm overall length) aren't worth distinguishing.
The 3rd is debatable but since it doesn't come up up elsewhere, I'm not sure it's worth our time.
