Does anyone know why there’s a second set of rails in the Landquart turntable offset 10°?
You can see them in photos since it was updated with the winch and capstans.

As best I understand, it's so the inbound track can be aligned to one of two outbound tracks opposite the inbound point.

One set are directly across the the table, straight.
The second set is a gentle curve.

Thus the table can be aligned:
Inbound at 6 o'clock, outbound at 12

Then jog the table only a few inches and:
Inbound 6 o'clock, outbound at 1 o'clock

I suspect, though I don't know, this was because the "12" and "1" o'clock tracks each can have multiple inbound/outbound traffic.
(I'm not well versed on the shops there- but if some of the leads into the roundhouse are for "parking only" and if one or two are actually tracks that extend onwards back into paint / maintenance / further storage - it makes sense to be able to run through with out shifting the table left/right every car length through).

Just grabbed this off Google Maps

I think the change was so that the Treibzüges (Allegras, Capricorns, etc) could pass over the table into the backshops without being disconnected.
(This is all conjecture on my part, but it would make sense with timing - upgrading the table with the second rail set as the railway takes delivery of the longer train sets?)

Sounds plausible. Easier than realignment of all the entry tracks with the ends being so close I guess.
Cheers Josh

I’d say spot on ;)
