Generally my experience is that sleeping children in buggies object quite vociferously to being folded up. My experience is also that other passengers don’t particularly welcome vociferous children...
II, this is an excellent suggestion. Providing freeform luggage space like this would improve travel for everyone with buggies, suitcases and bikes. These seats are inevitably only used on very busy services in any case.
AFAIK▸ , the child, sleeping or otherwise is meant to be removed BEFORE folding the buggy. I would expect the child to object vociferously if folded up with the buggy. Some makes of buggy have instructions that read "WARNING, REMOVE CHILD BEFORE FOLDING" Most children do not come with instructions.

Re post #31, yes I did read previous posts on this subject.
Looking at the scale of the chaos I still maintain that backup power supplies for signalling were insufficient. Lineside signals remote from control rooms also need back up power supplies. Up to a few miles distant, they could use power from the control center. Distribution of signalling power at 650 or 690 volts used to be the norm. When this is not viable then battery backup should be considered.
I also stand by my remarks that the new Thameslink trains are of a defective design if they can not tolerate a relatively rare but entirely foreseeable drop in line frequency. Is this design feature to be included in the Crossrail trains ? The thought of thousands of passengers trapped below ground for hours after a brief drop in frequency is rather worrying.

couldn't the multifunctional user space described above sell hot and cold drinks, sandwiches, confectionary and cakes all at the same time. It could even be fixed in position....... Not under present GWR▸ management as it would be contrary to their strongly stated policy regarding such matters. Might be worth considering by a future operator though. Extend all the 9 car trains to 10 car by adding an extra vehicle incorporating the new multi function area. About 40 or 50 seats in about half of the vehicle. The other half of the vehicle to consist of stowage for bulky articles and heavy luggage and an area from which refreshment may be obtained. At least a dozen tip up seats could be provided, primarily for those accompanying wheelchairs, baby carriages and the like. Place this vehicle in the middle of the standard class section in order that no standard class customer has to walk far in order to use it.

The report does IMHO▸ make very damming reading for the railway industry. It states that National Grid did not interrupt ANY traction current supplies. 25Kv AC traction current remained live throughout. A couple of 750 volt DC▸ traction current supplies failed, but only due to the RAILWAY OWNED transformer/rectifier units tripping out when the grid frequency was below normal.
The railway chaos as widely reported therefore seems to have two principle causes. Firstly the failure of the new Thameslink EMUs▸ to function with a lower than normal line frequency. It seems that this was NOT a "failure to re-start after the power cut" as was initially reported, there was no failure of the power supply. The new trains simply stopped working when the frequency dropped and could not be re-started by the driver when the frequency returned to normal. This to me looks like a grossly defective design if it effectively closes a main line for hours after a brief and entirely foreseeable drop in grid frequency.
Secondly, the failure of power supplies to signalling controls and to stations. These really should have standby supplies that actually work when called upon and permit of continuation of normal train services. The larger and more important facilities ought IMHO to have TWO standby supplies, one from the traction current and one from an "electrically distant" part of the national grid, in addition to the normal supply. Smaller and lower priority should at least have one main supply and one standby supply. In non electrified areas, a diesel generator is an alternative to the traction current.

Why not have a coach with no fixed seats, just tip up seats around the edges, an easy clean non slip floor, hand grabs for standing, plenty of room for cycles, wheelchairs, prams, buggys, Isambard props, or lots of standing cummuters from London to the west country... (and surf boards)
A bit OTT▸ to have a whole coach fitted out thus, but perhaps about one quarter or one third of a coach might be reasonable, it would be what we used to call the guard's van or luggage van, but would need re branding these days. "multi functional facility" or some such.

Because then if the first class coaches are at the front and back there would be no wheelchair access to the train.
Just goes to show the stupidity of cobbling two 5 car DMUs▸ together and calling it a 10 car train ! Did no one think of this problem ? Careful now, I have been told off for calling them DMUs. Even the MD insists that they are electric trains that can also use diesel power. DMU is considered a negative term that might in passengers minds be associated with shorter trains that lack buffets, padded seats, luggage space and other facilities found on inter-city trains. The sort of thing that used to be confined to branch lines or secondary routes, but these days they are infesting main lines.

Oscillation caused by the blast wave is IMHO▸ the most likely reason for the failure, or of course it might be unrelated and simply be coincidence.
The dust cloud seems unlikely to be the cause as the arcing appeared to start before the dust cloud reached the area. Also concrete dust is not conductive, unlike say carbon dust, AKA▸ soot, as might be spread by demolition of say a chimney.
