Arguments about how wonderful the HSTs▸ are aside, I suspect that the coming of the new trains in diesel mode will make for somewhat better services, and indeed that people will appreciate that. Of course, what's been scrapped is dramatically better services. Or will those plans be brought back in again in the lead up to the 2022 election?
Dramatically better? Just by being electric from Cardiff to Swansea? I can't see that, frankly.
On the politicians' presentation of it, I think the "handbook of sayable things" has a big influence. But I'd also start by questioning whether they have taken a decision to cancel all this electrification.
Imagine that they (and
DfT» specifically) would like to do more electrification. One thing that puts them off is that this are so very expensive, but then so is all infrastructure built these days. Say they press on anyway; the next step is to ask Network rail for costs and timescales (new or reviewed). But that leads to another problem, which is that whatever
NR» say obviously can't be trusted. So they can't commit to doing the work now. Maybe, after finishing what's underway (not just
GW▸ ), and if that works then doing the bits deferred to
CP6▸ , NR's credibility might have risen enough to decide to do more.
But for now, the government can't say "we have decided not to be decisive" - it's not in the "handbook of sayable things". So they announce it will not happen, but put the emphasis on what will happen, and how wonderful bi-mode is. That's just standard marketing or spin. OK, they risk sounding foolish to anyone who knows a little bit about the subject, but that doesn't apply to most of the voting public nor to the journalists poised behind their heaps of brickats.
