Tower wagon

When Geoff Quarmby took this photograph on Saturday 30th October, he didn't realise that it would be the last time he saw the tower wagon.

By the following Friday the tower wagon had been completely dismantled. The underframe will be re-used for the new tower wagon.
Here are a couple of pictures of the old tower wagon.

My understanding is that in order to comply with current legislation, the new tower will have two platforms but at a fixed height.
