This incident raises an important question, in relation to asset risk. If Pendos suddenly started collapsing to the point where they needed replacing, we're talking about AN EMORMOUS amount of required (and unplanned) new investment in the railway. One would like to think that this would fall at the door of the encumbent TOC or the asset owning ROSCO, but it wouldn't.
When the next West Coast franchise is up for renewal (2012?) if Pendos were failing, ALL THE FRANCHISE BIDDERS WOULD KNOW THIS and would factor this in to their bids for the franchise. Who would pick up the bill? The tax payer.
Now, this brings me on to the point of this posting. Are EMUs a good idea for inter city trains?
Now, my own answer to this is yes, but only if they work reliably throughout their life cycle of thirty years or so. If not, then isn't a loco hauled solution better? Imagine if the Class 91 had started to fall apart ten years in.
Eventually somebody would have had to take it on the chin and buy some new locos, but they would not have had the enormous investment of replacing the entire train sets.
So, is IEP a good idea, or would electric / diesel / electro-diesel locos and Mk V coaches be a much better and lower risk solution?
