Shown as follows in the current allocations :
511/512/513 all “Abgestellt RhB”
514 BR at Samedan as noted below
515 “Abgestellt LQ”
Presumably 516 doesn’t appear in the list any longer because it is being dismantled already.
When I was over there in mid-Oct two were dumped outside Reichenau-Tamins (I think) and a couple more in the sidings south of Chur. As I don’t really follow units I didn’t note which ones, but presumably they were 511/12/13/15.
I only paid attention to them because during a family winter holiday in Feb of this year, I remembered that the StNPs still had control of most Klo-Dav-Fil shuttles.
