LSWR E14 class : ウィキペディア英語版 | LSWR E14 class
The LSWR E14 Class was a class of 4-6-0 locomotive designed by Dugald Drummond for the London and South Western Railway. == Background ==
The indifferent feedback gained upon the release of Drummond's first 4-6-0 design, the F13 class meant that he went back to the drawing board to create a new, improved design. The LSWRs immediate traffic needs were covered to a certain extent by the 4-4-0 designs. This was because the F13 class 4-6-0 had been withdrawn from the heavy boat train services they were designed to undertake, as they were heavy on coal, water and man-hours in terms of upkeep.〔 However, the problem of continually accelerating timetables to the South Coast ports remained.〔 It soon became clear that another 4-6-0 design was needed due to their ability to ply their trade at faster speeds, and their inherent power-to-weight ratio.〔 This was true with the LSWR's passenger requirements increasing due to lengthened, heavier rolling stock that needed to keep up with faster point-to-point schedules. He also continued to develop a multiple-cylinder layout. The resultant design was to become the E14 class.〔
