Rail services have returned to normal after a 24-hour strike disrupted First Great Western services in the region.
Members of the RMT Union walked out in an ongoing dispute over the introduction of high speed trains in 2017. 30% of Sunday services were affected.
Further talks are being held in Bristol today in an attempt to avert another strike.
A three-day stoppage is planned over the Bank Holiday weekend by the RMT union, on top of yesterday's action.
The dispute is over the buffet service and the role of guards on new electric trains being introduced in 2017.
The RMT union has announced that Friday's strike planned for CrossCountry Trains has been suspended after "significant progress" was made in talks.
The action was being organised by workers in protest at a range of issues, including training, and the use of league tables to record performance.
