Rebuilding a withdrawn Class 47 into a Class 57

You are a heritage vehicle mechanical technician at a locomotive works. A withdrawn 1960s Class 47 has arrived to be remanufactured into a Class 57 — new EMD power unit, modern control systems, but reusing the original bodyshell and bogies. Your call: what can be safely carried over, and what has to be re-manufactured?

The donor locomotive is 35 years old. The Sulzer engine has already been lifted out; the empty engine room waits for the EMD 645 unit. The bodyshell and the two bogies are what you have to make a decision about. Reuse what is sound — remanufacture what is not. Everything you sign off carries the loco for another 30 years.
