The 4.3 miles (7 kilometres) Severn Tunnel which runs between England and Wales was the longest railway tunnel in the UK. However the Severn Tunnel runs under the river Severn, so therefore is not purely under land only. The Channel tunnel is longer, but is an international tunnel and therefore not only in the UK. The longest tunnel in the UK that is purely under land was until recently the 6,230-yard/3.5-mile; 5.7-kilometre Totley tunnel between Grindleford and Dore stations on the Manchester-Sheffield line on the outskirts of Sheffield in Derbyshire. This has now been superseded by the 10.120km (6m 507y) twin bores of the London 2 (east) tunnel, part of the Channel Tunnel Rail Link between Stratford International and Ebbsfleet International.

Alas, no. There are several longer. The longest of all, the Paijanne water tunnel in Finland, is a water supply tunnel so probably doesn't count.

However, those crafty Swiss are currently at work under the Alps, and the Gotthard Base tunnel (also a standard gauge railway) will be 35.5 miles long, a clear winner.
