Reading to London Waterloo is 37 miles (60km) it takes around 1hr 30m this route is short enough for TSW2 and it could give us a class 701 444 and 450 up closer to Waterloo area
Great suggestion which would give us SWR/SWT services and types as well as more activity at Clapham Junction and Reading which currently look deserted a lot of the time.
Possibly if it was to be made tho it would depend on how many trains the devs r willing to make, would be a good one tho
