Still, while their train indicators are still showing trains in the

IIRC that is not the fault of the new set up, the PIS on the whole route
through London Bridge and the Thameslink route has suffered from that for
ages...

All modern PIS systems, everywhere, suffer like that when there are a
lot of delays on the line. It's just more noticeable on Thameslink,
because the route is more vulnerable to performance pollution.

I reckon Thameslink is far worse than the SWML though [with which I'm
admittedly more familiar] - if mainline trains arrive out of order the PIS
invariably changes to match. I suspect the SWML's connection between the
train ID in the signalling system and the PIS works better.
