Paddington Station 24/7 series 3

A member of the public puts himself at risk by running along the tracks, all trains are halted while transport police chase the intruder. The installation of overhead cables and new ticket machines also cause delays.

The heatwave hits the network hard, with signalling equipment out at Didcot, rails in need of stretching in London and even the windscreen wipers are unable to clear all the insects hitting drivers' windows.

British Transport Police mount a special operation to stop criminals running drugs out of London. A cracked rail is discovered at Acton. A passenger falls between train and platform and police talk down a suicidal woman.

A vital piece of track insulating equipment fails throwing services into chaos. Engineers discover rotting wooden sleepers. Staff are shocked when a driver tries to start a train from the wrong end.

It's a tough start to Monday morning as weekend works at Acton have overrun, a lorry rips the safety barriers off a level crossing as it runs the lights, and 'the flying banana' trails the rails for defects.

Huge delays occur after a man is hit by a train at Southall, more chaos ensues when power to the track is accidentally switched off. Hundreds of rail enthusiasts descend of Paddington to see the Flying Scotsman.

A drunken man on the tracks forces a line closure. Engineers insert 24 huge culverts at Cowley Bridge near Exeter to ease flooding. At Paddington staff have to deal with tricky customers.

The bank holiday works schedule is disrupted when reports come in of a trespasser on the relief lines outside of London, forcing the cancellation of all trains leaving Paddington station. However, the total shutdown allows the engineers onto the track to renew large sections of the ageing rail infrastructure.

Staff spring into action when an unexploded WWII bomb is found near the line in Teignmouth, transport police question a man who jumped onto the track to retrieve something he dropped.

Station assistant Richard handles a medical emergency that may not be what it seems, engineers work round the clock to finish before bad weather hits, and the staff sit down for a Christmas lunch - of curry!
