A Better Picture
In this post, I said I might be able to get a better picture of the TBMs from a main line train. So today, I tried again.
I took a train to Ealing Broadway station and back again. I actually think if you want to take pictures it might be best to actually go to Acton Main Line, as the Oxford train, I got on return, went past the tunnelling site rather fast.
Note that each of the two tunnel boring machines consist of a large cutting head, with all sorts of ancillaries trailing on behind, like some giant tadpole.
I think that the gantries will be used to lift the machines to the portal at Royal Oak and support the conveyors taking out all of the spoil.
