Rush hour commuters battled a second day of travel chaos across the capital on the hottest day of the year so far.

South Western Railway announced on Tuesday that services in and out of Waterloo would be disrupted all week as temperatures soared above 30C in parts of the UK.

 

Sizzling heat caused rail tracks to expand meaning emergency speed restrictions have come into force.

 

The emergency speed limits, which will make journey times up to ten minutes longer, will remain in place until Friday. 

 
 

Delays and cancellations sparked yet another day of mayhem for passengers at London's busiest travel hub.

A fire under a train on the line towards Surbiton caused further issues.

Huge crowds of frustrated commuters were pictured staring up at information boards displaying 'cancelled' and 'delayed' notices.

 
 

Passengers described being unable to enter the station due to overcrowding while those trapped inside said it was "carnage".

One person wrote on Twitter: "This is beyond ridiculous."
