For some. Others accept them as fit for purpose.
It's so easy to just complain, so for those here who are complaining that the seats are not suitable for 'their' comfort, what savings would they suggest to pay for what they regard as suitable?
Whilst it's debatable how "intercity" a 700 is, I don't think anyone is suggesting any outrageous modifications to improve them.
Personally I find them the worst example of new build stock on the network, managing to bring together all of the most disappointing aspects of modern stock into one unit.
Seats wise, they use the basic version of a fairly unspectacular seat (in the sense it lacks much in the way of contouring/headrests etc and doesnt offer much padding), by omitting arm rests and seat back tables.
The trains weren't fitted with any full size tables from the outset.
Lighting is one of the worst examples of ultra-bright, white tinted LED, which lends the interior ambiance one of being sat in a dentists chair (just without the cushion or recline).
Luggage racks are poorly provisioned, in so far as the lack of lower shelf and curvature of the screens (combined with a lack of carpet) means larger cases have a tendency to roll out and across the train. If laid on their side, they stick out into the aisle.
The toilets are standard, but as with most Siemens units, manage to be just a bit more smelly and just a little bit more disgusting - perhaps the medical grade lighting helps the eye to catch all those things you don't want to see.
The ultra-wide gangways and sterile white plastic, lino-floored interior, give an internal ambinace that is much less comfortable travel and far more hospital waiting room - as though your sat awkwardly (in an uncomfortable seat), looking down a long corridor, waiting to see something unpleasant in the distance or receive some unwanted news.
Personally, the best part of the class 700 experience is the sigh of relief you take as you step off.
Now, how to fix a 700 at minimum cost:
1. Install yellow/warm tint on the LEDs.
2. Spec seats initially with arm rests and seat back tables at order stage (one of these has already had to be retrofitted after the outcry from long distance commuters who'd got used to the comparable luxury of a 377 - this mod probably costing more than just ordering a more deluxe version of the seat in the first instance).
3. Spec a warmer colour pallette for internal decor and (maybe) carpets for a midlife refurb. Something as simple as deep grey side panelling, rather than white, would make all the difference.
Obviously it's all down to personal taste, I'm sure there's a small cohort who see a 700 as a beacon of modernities finest offerings, but for me, they're utterly rancid places to be. I appreciate they're unpleasant but suitable for short hops across the capital, but to my mind, thoroughly inappropriate for journeys such as London to Gatwick, Brighton or Cambridge.
