The British Rail Class 07 diesel locomotive is an off-centre cab dock shunter used in Southampton Docks, to replace SR USA Class steam locomotives. It is a 0-6-0 diesel-electric shunter built by Ruston & Hornsby in 1962. They were originally numbered D2985-D2998 and later given the TOPS numbers 07001(D2985)-07013(D2997), D2998. ==Operation== This class was notorious for having the axleboxes run hot when travelling at high speed. This was initially encountered during delivery of the first locomotive, and subsequent deliveries were made by road. A later trial move of one Class 07 to Selhurst depot for tyre profiling also resulted in overheating axlebox problems and all subsequent moves of any distance, particularly those to BREL workshops, were made by road. This is in contrast to other shunter classes that would commonly have had their side-rods removed and traction motors isolated and would then form part of a train heading in the appropriate direction. Class 08s were commonly moved in this fashion at up to – overnight wagon-load trains being utilised if possible. For operation at Southampton Docks the Class was based in the former steam shed in the Old Docks near the River Itchen, work being carried out there by a fitter sent from Eastleigh. The members of the class that had TOPS numbering applied were also equipped with high-level air brake pipes, allowing them to move Southern Region Electric Multiple Units, and three locomotives were used at Bournemouth EMU depot for a period.〔 This was not their principal work, but they were often employed around their home-depot on general shunting duties. They were relatively fast for shunters and it was envisaged that they would be used to trip local traffic to/from Southampton docks. Accordingly, they were equipped, from new, with mainline headcode marker lights (six for the SR). In practice they were seldom used for this because of the hot axlebox problem, which also affected the possibility of the class working away from either Southampton Docks or Eastleigh. Numbers 2988, 2992 and 2998 were withdrawn from BR service without bearing TOPS numbers, and were cut up at Eastleigh works; 2988 in 1973, 2992 and 2998 in 1976. 2991, which was allocated the number 07007, was also withdrawn from capital stock before bearing its TOPS number, but remained in use at Eastleigh Works. Of the locos to bear TOPS numbers, 07003 and 07009 were withdrawn in 1976, and sold to P Wood of Queenborough, Kent; 07009 was exported to Italy,〔 and 07003 was sold to British Industrial Sand at Oakmoor, being subsequently scrapped in 1985.〔 07010 was sold directly into preservation, and the remaining locos were sold for industrial use during 1976 and 1977: 07001 to Staveley Limeworks, Buxton; 07002/6/12 to Powell Duffryn, Kidwelly (where 07002 and 07006 were scrapped in the 1980s); 07013 to Dow Chemicals, King's Lynn.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「British Rail Class 07」の詳細全文を読む スポンサード リンク
