Hi David, and welcome to the forum. I hope we can help you. If you have pictures of your 3556 it would be helpful for the members to assist more effectively. One from each side, and one from the bottom would be a good start.

Koll's catalog has the following description of the 3556 (I translated it from the original German): E-locomotive, wheel arrangement (1'C) (C1), series Ce 6/8III of the SBB, "Crocodile," blue-green, cast, gray chassis, three front lamps on both sides, 2 STA (16), fittings for STA, rail signs, manufacturer number 14305, yellow stopping poles, wheels blackened, K 7.1 1989-1993.

In German:
E-Lok, Achsfolge (1'C) (C1"), Baureihe Ce 6/8III der SBB, "Krokodil", blaugrun, Guss, Fahrgestell grau, beiseitig 3 Stirnlampen, 2 STA (16), Stutzen fur STA, Meallschilder, Beter.-Nr. 14305, Haltestangen gelb, Rader geschartz, K 7.1 1989-1993

The two "STA" are the versions of the pantographs on the roof; the "K 7.1" is the type of coupling

Hi David, welcome to the forum.

The 3556 has road number 14305, a metal body, and was produced from 1989 to 1993.

As far as I can remember, only the 3056, and the 3356 with road numbers 13302 and 13303 have a plastic body.
The 3356 has been metal since 1993 (mostly 13305).


My 3556



Does your loco have a sticker with a serial number on the bottom?
The 3556's number should start with the letter R.

Hope this helps to identify your loco.

Here are some pictures

I will try to make better ones when I can
