School trip using the train and undergroud

[Tiredandtorn]

Dcs school is planning a museum visit using the train and underground. Given the climate, we're a bit uneasy about this. The school says a coach is too expensive and takes too long.
What are your views on how safe this is? I'm very confident in the schools ability to deliver the trip, adult/child ratios safely etc. it's the mode of transport... Dc is year 4

I commute 4x a week, we take DD on a regular basis into London. She went with the school several times with public transport as the school is in walking distance to a direct train line.

Yes, there is a bit more police around but otherwise it is business as usual. The actual alert is - as far as I know - not raised and unless there is a direct threat putting my life on hold is not an option.

I commute into central London 3 times a week. It wouldn't even occur to me to stop my daughter going on a school trip to London because of terrorist threats. She is also in Year 4.

She is at far more risk every day from the maniac parents on the school run who park badly all over the pavement as she is walking past or rush at the zebra crossing outside the school every day.

Think of the millions of people who actually live in London.

I wish our school would do this rather then dragging them into town on the coach, would take a fraction of the amount of time and save a fortune.
