Railway Signs and Signals of Great Britain


A non-standard differential permanent speed restriction sign alongside the Down Main line at Princes Risborough. On the right, the lower board shows a maximum permissible speed of 65 m.p.h. for 'Sprinter' type trains, while the upper board indicates a lower limit of 40 m.p.h. for all other trains. On the left, the 15 m.p.h. board with the left-hand directional arrow applies to moves onto the Thame Branch Siding. (Photo taken 16 January 2008, by Jo Sharpe.)
