James Cudworth, the Locomotive Superintendent of the SER. The return journey took 70 minutes. The Royal Train visited the line again on 18December 1849 conveying Queen Victoria and Princess Alice from Windsor, Berkshire to Tunbridge Wells on a visit to Princess Louise. The journey via Waterloo took 100 minutes. The train was driven by William Jacomb, Resident Engineer of the LSWR, and Edgar Verringer, Superintendent of the LSWR. At Waterloo, driving of the train was taken over by John Shaw, General Manager of the SER and Mr. Cockburn, Superintendent of the SER. The return journey took 105 minutes. With the opening of the extension to Robertsbridge, there were three trains a day, with two on Sundays. These were augmented by an additional train daily when the extension to Bopeep Junction opened. In 1860, there were seven up trains and six down trains daily; Hastings to London via taking two hours. From 1861, Cudworth 2-2-2 "Little Mail" class locomotives were introduced. In 1876, the Sub-Wealden Gypsum Co built a long line from a junction south of Mountfield Tunnel to a gypsum mine located in Great Wood, Mountfield. This line was still in operation as of 2007. Bogie carriages entered service on the line in 1880. In 1890, the winter service was eleven trains each way, of which five were fast. An additional two trains daily operated between Tunbridge Wells and Wadhurst. By 1910, this had increased to twenty trains each way, of which twelve were fast, plus the extra two Wadhurst services. Four trains ran on Sundays. The service was reduced during World War I, but Sunday services had increased to seven by 1922. By the 1930s the line was worked by L and L1 class 4-4-0 locomotives. The Schools class 4-4-0s were introduced in 1930; the width of these was measured across the cab, and measured across the cylinders. The service was again reduced during World War II, with fourteen trains daily in 1942, of which four were fast; there were seven trains on Sundays. As built, it was envisaged that the West Country and Battle of Britain class locomotives would be able to work the line. Forty-eight locomotives of the West Country and 22 of the Battle of Britain class were built with cabs that were wide and paired with tenders of the same width. It was subsequently decided not to work these locomotives over the line. Locomotives from
