It's a shame to see a good bit of bickering and slightly off-topic conversation about whether people like Steve Coogan or not has got in the way of the facts.
The train wasn't short formed. The portion from Littlehampton is usually less busy than the portion from Eastbourne - people could have waited 5 minutes and walked through to the Littlehampton portion after the attachment at Haywards Heath.
First Class accomodation is for First Class ticket holders only. End of story. If passengers want a better chance of a seat..guess what.. they should have gone to the ticket office before their journey began and bought a First Class ticket.
It's not 'end of story.' Irrespective of the facts of this particular case, if trains are frequently overcrowded so that people have to stand, first-class accommodation should be abolished.
Passengers jammed into cattle-truck conditions may have been totally unaware that another 4 coaches would later be attached. Even if they were aware, would there be enough time to get off one set and onto the next? Would the rear set prove to be full if they tried?
If one set was full and one not so, were there no announcements made at Haywards Heath and time given for passengers to move to the more empty set? If not, then this is a "fail" by the TOC. If both sets were jammed and First not declassified, again a "fail"- especially as such a "fail" would have rewarded the TOC financially (paying compensation to 1st class ticket holders).
I would personally remove free first class travel from all rail employees (including/especially senior managers), give them standard class only, and for TOCs and Network Rail make it a condition of their job that staff who are not on shifts travel to and from and within work by train, and not allow their senior managers working hours which would allow them to commute outside the peak. Perhaps then whilst regularly travelling standard in a ram-loaded train they would have a little more sympathy with the people who pay their own money to travel on the train and too-often are jammed in like sardines, and be motivated to do something about it (in fairness most Guards and other traincrew fully understand as they see it, but I do wonder sometimes about the middle-managers and above). I would do the same with all the DfT people involved in rail.
I remember once a senior TOC chap describing an annual season ticket purchase on the South East commuter lines as "the ultimate distress purchase." Seeing as this is the case, the usual mechanisms of accountability don't work on many TOCs (i.e. people are only on the train in the first place as they have no other option), so there really needs to be some stringent and reliable passenger satisfaction performance measure to which senior managers bonuses and in fact basic pay are linked. Only when senior management (and indeed middle management) are properly accountable and thus incentivised in their own pocket will things improve.
