26726:

Swedish train set, manufactured 2001-2002.
I bought it primarily because trains like this frequently could be seen in Norway.

The locomotive

26726-1, SJ Rc 2 1012:

This locomotive is version 2 of Märklin 33411, only sailable in this set.
i have installed a current conducting coupler at end 2, to supply the coaches with current for interior light, controlled from the decoder function 1.

The coaches

26726-2, SJ Ao 2-L 5139 

This model is Märklin 4072 version 4, only available in this set.

26726-3, SJ Bo 5-L 4947

This Märklin 4072 version 5, only available in this set.

26726-4, SJ RB 02-L 4845

This restaurant car is listed as version 4 of Märklin 4073, only available in this set.

I generaly find these models very light.  On my test layout they easily derails, so I will maybe find a way to increase their weight a little bit.
I also have plans to install interior light, powered from the locomotive.
