This set was produced in 1990 and 1991 as a limited train set for Luxemburg.
Locomotive CFL 455:
This model is version 4 of Märklin 3136
2846 may contain version three or four of this locomotive. The difference
is as far as I know only one:
Version 3: the number plate on the front end is 9 mm wide
Version 4: the number plate on the front end is 7 mm wide, mine is 7 mm.
The trackCleaning car:
This is a unique car for the 21846 train set. The pick-up shoe is
installed by me.
Except for the Christmas car 48401 from 2001 I have not seen this design
used on other Märklin cars.
The tank cars:
This car is version 8 of Märklin 4644
This car is version 9 of Märklin 4644
This car is version 10 of Märklin 4644
I have converted the train set to digital operation, see 2846.htm
