I recently bought some new pickup shoes from ebay, and while one of them is the correct shoe for the train i have (although it was the wrong one delivered) I also ordered a second one, which due to my own fault is wrong. how much of a big deal is it i put a longer/shorter pick up shoe on one of my Locos?

Hi John

The length of pickup shoe is important when you must guard against short circuits that will occur when crossing switches and the pickup shoe hits the chassis frames and short-circuits the system. but try them on the model and if they do short-circuit, then you will have to get the right pickup shoe

The lenght of a particular pick up shoe has a specific reason to be replaced on a loco and to replace it with a different lenght, positioned hole can only cquse problems.

Couldn't see that putting a shorter one on would be a problem, but a longer one might have problems with the "outside throw" (the standard rail term for the outside extremity as it runs into or out of a curve).

Most of the older loks had contact plates built into the bogie. These plates would contact the metal flaps folded on the topside of the slider mounting plate. The spacing of the contact flaps on the sliders is different for the short and longer sliders. This could result in either a short between the slider and the bogie or result in poor contact between the slider and the contact.
It is also possible that a larger or offset screw mount slider could result in the slider contacting the adjacent axle(s), causing a short. This may not happen all the time, but may occur when the slider is pushed up (over switches, incline/decline, etc).
I would recommend using the slider listed in the spare parts list for that model. For Maerklin, this information is included in the instructions for each model. You can save the other slider for eventual replacement of an appropriate one.

Further to what Mike C says, I the dummy one, took off a shoe to see about oil on the Micheline bus (3124?) and when replacing the shoe put it on IN REVERSE.

When I fired up the bus, it would not RUN!

Since that was the only change I made, I knew my problem, and reversed the shoe. All was well again. Sometimes small changes can be REPAIRED?

Thanks for the help guys, I ended up ordering one from a store on Ebay. The shorter one I ordered by mistake also had a shorter mounting plate, so the little folded over flaps shorted out. Runs alright now, I think I just need to go nuts on track cleaning, maybe order the track cleaning car from Lokshop might be easyest.
