Hello all, this might not be the place for this. But anyway, as a few of use will know the Midland Railway made famous use of a 'Small-engine' policy, this doctrine set out by Darby called for numerous short trains hauled by 0-6-0s and 4-4-0s, with double heading common place. This largely conservative take on Locomotive development was the famous source of the numerous delays suffered by the Midland network and of the image of vast plodding coal trains. The Midland clung on to the policy right up to the Grouping and the stanch refusal of derby to seriously recognize the need for change crippled the LMSR in it formative years. At least that is my understanding of the situation.
Yet paradoxically the Midland did produce two famous 'large locomotive' designs, the famous S.D.J.R 7F 2-8-0 and the equally well known 0-10-0 banking locomotive for the Lickey incline "big bertha" and from what I can tell there every suggestion that, in particular with regards to the former, that the best of Derby practice had been carried over to the Somerset goods. The Midland was very good at producing simple and rugged, if small, machines. For Example the 3F 0-6-0 which endured right up to the 60s, some thirty years after the company that had created the design had ceased to exist.
This has left me wondering, what could have forced the Midland Railway to have abandoned its small engine policy sooner? One idea was for the L.N.W.R to have a direct link to Derby, putting a sword jabbing at the Midlands heart. Another was for the MR to have directly absorbed the S.D.J.R, thereby forcing the requirement for larger machines.
Please let me know what you think.
Yours
