Which Versas are doing this then a matter of interest? And don't say all of them, as that's not what was seen in Shrewsbury with them all. Granted some of the Versas were kept on locals more often than not as were quite poor, 2977 certainly springs to mind as been somewhat poor, but some could shift fine at speed on interurban routes and were allocated when needed, despite not seen suited. I'm not disagreeing they are end of life, but Shrewsbury certainly knew them inside out and kept them on the road. Tamworth had the knack of killing off 2964 and 2996 the later was a real slow one!
Pulsars out of Leicester would probably have been a much better option for Tamworth over Versas that been said, particular for interurban work. It would have been thought Versas were really for locals, so why all the Citaros and Pulsars doing locals?
On the positive note as said, investment is coming.
