Regarding the Valenta vs. MTU issue, although not a directly compatible comparison (and I would not even claim that), in general terms it might be compared to the demise of steam in favour of diesel - well behind continental and across-the-pond operators, it must be added (not to mention electrification :roll

.
Getting from steam to diesel traction was similarly the only sensible thing to do, but that didn't stop many from damning the decision, if only for the aesthetic or traditional reasons, however vaguely justifiable in real terms. Perhaps the last steam locos delivered to BR could have been retained in service longer, perhaps not. In addition to retaining doubled support infrastructure alongside diesel, with the costs involved, steam traction is of course ecologically rather disastrous. Into the 1970s with a sizable steam fleet? Hmm.
The number (and success) of heritage railways is nevertheless an indication of the continuing love affair with steam traction. And why not.
Naturally the retirement of a vastly larger steam fleet led to many more terminations than the economic boondoggle of continuing Valenta use, if only for the more time- and manpower-consuming upkeep of the steam locomotives. Nevertheless, the extreme example shows that workforce is not necessarily the winning part in such changes - in the case of Valenta the improved operating costs for a company enable the continued employment of staff. But could there already be a next development around the bend (or curve) that could lead to layoffs due to technical or workforce-structure "improvements"? (Even more) integrated loco/rolling stock fault self-analysis systems to reduce servicing man-hours? Change of franchising rules to allow a reduced number of bid winners (semi-rail-monopoly) and resulting streamlining along with reduction of departures or services on-board - who said buffets (although a forcibly sectioned franchise model might still reduce the # of staff that can be made redundant to keep a minimum service level within any geographical franchise)?
So, to stop the soliloquy

, everyone's entitled to their opinion and that goes for Valenta-lovers too. I personally know which sound I prefer, but if the change to MTU is what keeps the still-modern-looking 125 fleet on track as well as the professionals employed, I know which I prefer.
So, for the last time: Ffffffffffiiiiiiiiiiiiiiiiyyyyyyyyyyyyyyy.
