With the line linking Mariazell system to Ybbstalbahn system at Lunzer See station it allows me to have all the 1099's narrow gauge electric locos . I also have a few in fantasy liveries ( you never really see this in UK modelling) . Here is a line up on my diorama backscene .

These locos run from fiddle yard one to Lunzer and then into the electric holding sidings before being replaced by a diesel for the run to Waidhofen .
They are also used in my small eletric terminal exhibition layout- Gusswerk.
