LSWR P14 class : ウィキペディア英語版 | LSWR P14 class
The LSWR P14 class was a class of 4-6-0 locomotive designed by Dugald Drummond for the London and South Western Railway. == Background ==
The continuing need to grasp the nettle in terms of Drummond's first two 4-6-0 classes meant that he went back to the drawing board to create another design. The LSWR's immediate traffic needs were covered by the relatively successful G14 design of 1908, though with only five locomotives in the class, they were unable to undertake the haulage of all heavy boat train services.〔 However, the problem of continually accelerating timetables to the South Coast ports remained, and the G14s were in dire need of assistance from a new class of similar design.〔 The design's proven ability to ply their trade at faster speeds, and their inherent larger power-to-weight ratio on other lines meant that Drummond once again decided to persevere with the concept.〔 He also returned to a two-cylinder layout with what was to become the P14 Class.〔Haresnape & Rowledge (1982).〕
