STEPHENSON (Robert 1805-1859 Railway and Civil Engineer)
STEPHENSON (Robert 1805-1859 Railway and Civil Engineer) Fine Letter Signed "Rob. Stephenson", to "Dear Sir" [the Secretary to the Board of the London and Birmingham Railway],  "On Saturday last I examined the Leighton Tunnel and found the whole of the work in perfect order ... At four or five points water percolates the brickwork rather freely which during the winter freezes and forms large icicles detaching at each thaw a thin layer from the brickwork... The slightest examination is sufficient to prove however that the bricks are hard and sound throughout and not at all affected by the pressure",  3 June 1842

The tunnel consists of three bores 272 yards (249 m) long. The central bore, the tallest, carries twin tracks and was built for the London and Birmingham Railway in 1837. It was this part to which Stephenson's findings refer.
