This Easter (8-23 April) Network Rail will be undertaking rail improvement work in the Bath area impacting on the ability of GWR to operate the usual train service.
Network Rail will widen the platforms at Bath as part of the ongoing infrastructure works linked to the introduction of GWR’s new IET trains and electrification.
On the weekends of 8-9, 14-17 and 22-23 April Bath Spa will be closed.
There will be no trains between Bristol and Bath, Chippenham and Bath or Trowbridge and Bath.
Throughout the weekends buses will replace trains between Bath and Chippenham, Bristol, Bradford on Avon, Trowbridge, Westbury and Frome. Stopping buses will serve Freshford and Westwood (for Avoncliff), Oldfield Park and Keynsham. A Castle Cary to Bristol service will also run to connect in/out of Weymouth line services which start/terminate at Westbury.
During the working week (April 10-13 and 18-21) only one platform will be available to run trains so a revised train service will operate with trains between Bristol Temple Meads and London Paddington via Bath and Chippenham will operating every hour.
Great Western Railway urge all customers to check travel arrangements by visiting www.gwr.com/Bath2017 and consider travelling on the Fridays and Mondays.
Information is available at all stations and on all journey planners.
Lower Bristol Road has reopened following the earlier car crash.
First buses aim to have a full service by this afternoon.

To allow for electrification and Crossrail works Paddington Station will be closed over Christmas.
There will be a six-day closure, starting on Christmas Eve, Saturday December 24 through to Thursday 29 December.
Trains are likely to be very busy on Friday 23 December, and it is recommended that customers book ahead and travel early if they can.
Trains will start and finish at Ealing Broadway throughout the closure with customers completing their journey by London Underground. There are no lifts at the station and it is recommended that customers who find using Ealing Broadway difficult, to change trains at Reading and travel to and from London Waterloo. South West Trains have agreed to accept GWR tickets to support this.
Full details are available here including details on travelling with bikes, sleeper services and Pullman dining service.
Network Rail will be deferring four parts of the Great Western electrification programme.
Schemes affected include the Thames Valley Branch lines (Henley and Windsor), Didcot to Oxford, Bath to Bristol Temple Meads and Bristol Parkway to Bristol Temple Meads.
The full statement can be read here.
As part of the ongoing improvement to the network, Great Western Railway will have some changes to their services over the holiday period. The biggest change is that London Paddington will be closed to all rail services from Saturday 24 December to Thursday 29 December.
This means that GWR rail services will be starting and finishing at Ealing Broadway, where customers can make a connection to the underground or take scheduled bus services into London.
"Ealing Broadway does not have step-free access. We are therefore recommending that customers on our Bristol and South Wales services, who are travelling with heavy luggage, children, or who find steps difficult to change at Reading and use services from there to London Waterloo. This will mean a longer journey and we will be alerting customers to the changes well in advance so they can plan ahead."
Full details of the planned works can be found on the GWR website.
From Monday 12 September to Friday 21 October 2016, the Severn Tunnel will be closed to enable electrification through to Cardiff and Swansea.

Newport to London services will be diverted and replacement buses will run between Newport and Bristol Parkway.
Alternative timetables will operate, with journeys from Newport to London taking about 35 minutes longer and Newport to Bristol 45 minutes longer.
Throughout the period the rail replacement coaches will be running between Bristol Parkway and Newport as well as Bristol Parkway and Severn Tunnel Junction, with multiple coaches and standby vehicles on all peak services.
Arrival in Parkway and Newport is set to meet the majority of connections where a full train service will run.
There will be extra customer service staff at all locations with information on connections.
