| Remarks: The Single Fairlie type possessed flexibility which made them particularly suitable for severe curves and light track. These 'Singles' were more servicable than the earlier Double Fairlies, in that they had only one boiler and one driving bogie, instead of two, with the corresponding reduction in maintenance costs. They gave a good account of themselves on grades of 1 in 35-50, abounding with curves of 5 chains radius. Although designed for mixed trains at maximum speeds of 20-25 m.p.h., they were sometimes employed on express trains, with surprisingly good results. |
