This is a simulation based on what actually happened on 22nd July 2023. It is worth noting that this day was an RMT strike day so services are very limited.

GWR operates a roughly 2 hourly service between Plymouth and London Paddington, and Plymouth and Bristol Temple Meads. There are no services towards Penzance.
CrossCountry operated one service from Plymouth to Leeds, as well as two services originally from Derby to Plymouth which only ended up running from Burton-on-Trent due to them both being late from Central Rivers TMD.

The first service is 5U10 03:33 XLZ - PLY with the last service being 5C94 18:15 EXD - PLY arriving 19:07, there are no services outside of these times.

5V44 and 5V46 terminate on Platform 5 around midday with no onward working, this is intentional as they were stabled there overnight to form 1S47 10:27 PLY - GLC the next day.

Other services towards the end of the timetable terminate at Plymouth with no onward working, again this is intentional as they were also stabled at the station overnight.
