I had an e-mail yesterday from GWR▸ outlining further service improvements from 6 July.
They include:
Half-hourly service on the St Ives branch line restored 7 days a week
Half-hourly service restored on Exmouth-Paignton services Monday-Saturday
Normal service level restored on Falmouth branch Monday-Saturday
Majority of services restored on Cornish mainline between Plymouth-Penzance Monday-Saturday, getting us closer to two trains per hour throughout the day. This has helped to fill the early evening gaps on that were raised for Saltash and St Germans. We have also been able to make some additional calls on Sunday services, but these remain broadly hourly
Interesting, Richard. If you put Plymouth to Penzance on Monday 22 June (but not before) into the National Rail Enquiries Journey Planner search you get the half-hourly train times as per the pre-COVID timetable.
