The voyagers and their like are another problem with poor planning......
Voyagers are just nasty trains full stop, but sadly we're now lumbered with them for the next gawd knows how many years.
Lots of smaller trains take up far more capacity on the network than single larger units.
Train length is constrained by platform length though. Network capacity is affected by a lot of things including the mix of trains using the route, and signalling capability.
It would be possible to buy carriages cheaper than these powered units, allow adequate space and improve network capacity!
Adding un-powered trailer cars into existing units is generally not an option because it reduces acceleration capability that timetables have now been written around.
The cost would also be minimal - In 2004 SouthWest Trains alone had 300 units "nn storage" because they were unable to run as the power supply was incapable of meeting the demands of the units. No-one though to check!!!
The SRA footed out another 7.2 million in storage costs on top of the wasted purchase price!
The purchase price wasn't wasted since the trains are in service.
There is aso the reliability issue - in some cases this new rolling stock breaks down every 2,400 miles (First Great Western) on average compared with 24,000 miles (Connex slam doors) for the old rolling stock!
Its all very well quoting miles per casualty, but a lot of modern stock is now exceeding 24,000 mpc. It isn't just a function of the rolling stock either - other operators use the same stock as FGW without any major issues.
As for the costs of spaces - they are actually low!
Incuding running costs, leasing costs, interest and maintenace the actual "cost" of each seat to the company is (aacording to Transport Watch UK) £600!
So anything above that is a profit!
Sounds very low to me - I'd be surprised if that even covered just the leasing cost. On top of whatever the rolling stock costs are there's running stations as well. Also factor in that if you give over a third of a carriage (say) to bicycle carriage, that's a third of a carriage not generating passenger revenue, which any operator would also take into account.
