My main concerns about this, and similar long term incidents are the lack of emergency lighting and public address equipment.
Post #44 suggests that this is now being addressed.
In most public buildings there is a legal requirement to provide emergency lighting, usually for 3 hours, yet on trains it seems to be optional.
The power required is very small and is easily supplied from batteries of modest size, weight and cost.
With modern LED lamps, 10 watts should provide ample emergency lighting per coach, a battery to supply 10 watts for 3 hours is a cheap, "off the shelf" item, 6 hours would be better, and still very affordable.
Chemical light sticks or battery lanterns are other possibilities, both are cheap and readily available. It seems that chemical light sticks are now being provided.
Public address systems likewise do not need much power and I fail to see why battery operation for at least 6 hours is not allowed for.
I would estimate that a power supply of 5 watts per coach would give ample audio volume, and since the equipment wont be used continually the average power demand is far less.
Presume the equipment is used 25% of the time, that is an average loading of 1.25 watts per coach, or 5 watts per 4 car unit. 6 hours operation would require 30 watt hours. A battery to supply 30 watt hours is a small and cheap item that should at least 5 years and probably longer.
Functioning PA and emergency lighting would make conditions a bit more tolerable, but wont actually normally reduce the delay.
It would seem that planning for hauling or propelling the failed train could have been better. On an intensively used urban route, should it really take hours to haul or propel a failed train at walking speed to the neaerest station?
IMHO this FCC breakdown was far worse than the recent FGW breakdown near Pewsey. The FCC incident no doubt could have been better handled, but was mitigated by being out in the open, and with functioning lighting, and air conditioning in at least part of the train.
What if someone was taken seriously ill ? in the FCC episode they could well have died in the dark crowded train, even first aid would be problematic in complete darkness. In the FGW breakdown, the air ambulance could have saved a life if need be, not much help in a tunnel though.
BTW, am I the only person who allways has a torch with them on public transport ? (two on FCC !)
