The Kilsby Tunnel is a railway tunnel on the West Coast Main Line railway south of rugby on the main line ( not the northampton loop )in England. It was designed and engineered by Robert Stephenson.

The tunnel is located near the village of Kilsby in Northamptonshire roughly 5 miles (8 km) southeast of Rugby. The tunnel is 2,432 yards (2,223 metres) long.

It is today the 18th longest tunnel on the British railway system.

The North Portal is visoible from the A5 just North of Kilsby Village ( http://www.streetmap.co.uk/newmap.srf?x=456500&y=271500&z=3&sv=kilsby&st=3&tl=Kilsby,+Northamptonshire+[City/Town/Village]&searchp=newsearch.srf&mapp=newmap.srf ).

I am not sure that you can get an easy picture of trains emerging from the South Prtal as the local narrow road goes over the top of the south portal.
