ETS2 - Vigo - Accessible railway sidings

There's a cool freight sidings area below a roundabout in Vigo, Spain. Would make a great pick up and drop off point. Some quite narrow gaps make it a fun place to manoeuvre. It would be great it trains rattled through there as well!
I was expecting the large picturesque roundabout to give more access, but no - a giant slab of perspex stopped my progress. I'll have a poke around and see if I can get to the rail passenger terminal. Looks cool over there too.
