Also saw two units this morning as I passed Reading depot this morning, but as one was partly in one of the sheds, the other hidden behind the Sleeper stock, I couldn't see if they were complete.
Is it odd that they are being moved by road?
The story goes that they were due to go north by rail on the day Nuneham viaduct was closed. Indeed, one of them was the last train over it - so possibly the last train that broke the camel's abutment. They were not cleared for any of the alternative routes, and in any case must have been the lowest of priorities for getting a path, so were stuck where they were. Logically, by now it would be worth waiting for reopening day. So most likely they have now reached some required maintenance, and avoiding that is worth the road transport cost.
