South Western Railway (SWR) is urging customers only to travel by rail if absolutely necessary on Saturday 1 and Sunday 2 October due to the planned RMT and TSSA industrial action.  

Customers should expect severe disruption on the network and, if they must travel on either of those days, should seek to do so by other means. 

The London Marathon takes place on Sunday 2 October and SWR is advising runners and spectators to Check before you travel. 

SWR has published its strike day service levels for Saturday 1 October, which will provide a severely reduced service on the routes Network Rail has made available.  

Significant parts of the network will be closed entirely and those trains that are running will be far less frequent and much busier compared to normal. 

Unlike during previous strike days, on Saturday 1 October, trains on the Windsor Line will run two per hour and terminate early at Feltham. This is due to planned £375m Network Rail engineering upgrades which, once completed, will enhance future services on this line for many years to come.  

Due to the impact of the strike day, customers are also urged only to travel if absolutely necessary on Sunday 2 October, when first trains will start much later than usual across the network and are likely to be very busy.  

Staff at Network Rail, more than 2,100 SWR members of the RMT union, and SWR members of the TSSA union are set to take strike action on Saturday 1 October, causing severe disruption. 

Network Rail will provide contingency cover for critical roles including electrical control room operators, signallers, maintenance, and response teams, but will not be able to cover the whole day. 

SWR's reduced timetable will run from 07:15 to 18:30 on Saturday 1 October, and will consist of:  

• Two trains per hour in each direction between London Waterloo and Feltham  
• Two semi-fast trains per hour in each direction between London Waterloo and Basingstoke 
• Four trains per hour in each direction between London Waterloo and Woking 
• Two fast trains per hour in each direction between London Waterloo and Southampton Central 

Trains will not stop at all the stations on these routes. There will be no SWR services across the rest of the network. 

SWR drivers will not be involved in the planned ASLEF strike action on Saturday 1 and Wednesday 5 October. However, customers should check before they travel, as their connections with other operators might be impacted, or not run at all.   

"I'm sorry that due to strike action we must urge our customers to only travel if absolutely necessary on Saturday 1 October and Sunday 2 October. Those needing to travel should seek to do so by other means.  

"Large parts of our network will be closed on the strike day and there will be a late start up on the morning after. Those who must travel are urged to carefully check the times of first and last trains and avoid them if possible as they are likely to be very busy. 

"We are grateful to our customers for their continued cooperation, patience, and understanding as the rail industry works to bring this damaging nationwide strike action to an end."
