The LB&SCR I1 class was a class of 4-4-2 steam tank locomotives designed by D. E. Marsh for suburban passenger service on the London, Brighton and South Coast Railway.

They were not a great success in their original form, being poor steamers, but all of them passed to the Southern Railway in 1923. Between 1925 and 1932 they were rebuilt by Richard Maunsell with new boilers which greatly improved the performance. The rebuilt engines were designated I1x class.

Numbering

The first ten were numbered 595-604 and the second ten were numbered 1-10. The Southern Railway initially added a "B" prefix to these numbers and later renumbered them 2595-2604 and 2001-2010. A few I1x class locomotives survived into British Railways (BR) ownership in 1948. BR added 30000 to the numbers but it is believed that only 32005 actually carried its number. All had been withdrawn by the end of 1951 and none has been preserved.
