I offer no definitive opinion on franchises, but I am getting tired of having the same old arguments about the subject (on different threads)...
The main problem with these arguments is that (whilst there are a million things wrong with the current set up of franchises) there's no clear alternative that doesn't come with a million other problems).
Nationalisation? Instead of using the "1980s BR" as a template, imagine a modern state owned railway being similar to the fragmented/ partly privatised/ underfunded/ awkward situation that we see with the modern NHS/ schools/ Post Office. Are we prepared for that?
A modern "state owned" railway wouldn't be one big happy family, where the Government give a cheque to cover five/ten years operations and never interfere (whilst allowing "proper railwaymen" to get on with the job - whoever they are).
With the best will in the world, it'd be fragmented - even BR had different sectors and different hierarchies. What's the alternative? Longer franchises can mean stagnation, shorter franchises can mean short-termism. Until someone can come up with something better, I have to accept that the current model is the "least worst" option.
(and, in the grand scheme of things, I'm not worried about the cost of repainting trains every five/ten years or the cost of rebranding station signs)
the inability of one TOC to quickly deploy rolling stock that is idle yet belongs to another in order to satisfy some contingency issue is also symptomatic**
(** Example: A few years ago on a Sunday morning at Sheffield, a London-bound train failed at Derby depot prior to its empty stock run to Sheffield. Thus "they" had at least 30 minutes warning before the scheduled departure that this train would not operate. What happened was a bus was laid on to Derby. What would have happened in all probability in nationalised days - and should be the case now - is a spare DMU would have been fired up for the trip to Derby. Why this did not happen was because the spare DMUs belong to another TOC.)
Even if we had one big railway, you'd face problems in a situation like this.
Who at Sheffield is trained to take a 142/ 143/ 153/ 158 (or other type of DMU commonly found to be "spare" at Midland Station) to Derby? If it would mean taking stock on a route that it doesn't usually go along then would you need two drivers in the cab (one with traction knowledge, one with route knowledge)?
Is the stock permitted on that route (Pacers can't go south of Chesterfield, AIUI)?
Even if the 75mph DMU can get from Sheffield to Derby in the path that the 125mph train was due to take(?), is there a spare path back (slotted in between the various Voyagers/ Meridians?
Have you got time to couple two or three Sprinters/ Pacers together to ensure that all passengers on the InterCity service get a seat?
What was the "spare" DMU and the two(?) members of staff due to be doing? You may have spare DMUs sat around on a Sunday morning, but you wouldn't normally have two spare drivers "idle" on a Sunday morning (or available at just thirty minutes notice). Sheffield to Derby and back may mean being away for a couple of hours (depending on paths), which is going to knock later services out of synch (drivers and stock in the wrong place).
Maybe this is more of an argument for "we should use the same kind of stock on local and long distance services, so that we can tap into spare resources" (which, for me, is more about having one big fleet of unpowered coaches, or maybe about having significantly more "spare" resources for such emergencies). Otherwise, much easier to stick on a coach (since a coach driver doesn't have to worry about route training or finding a path on the motorway.
