I was told that the building was for the rear entrance to the railway works and housed the clocking in machine. You can see from the brickwork mis-match in the wall on the photo where there was an opening to enable access.

It is a building on the access to the railway works and was used as a timekeepers/clocking in/out place.

I always thought this was a gatekeeper/timekeeper’s office for the old locomotive works. By the side there is a bricked up doorway that would have opened onto New England Road with steps going up to the level of the works. I remember seeing an old photo of workmen walking down New England Road under the goods line bridge, I would think this was one of the entrances they were coming from.

Thanks for your comments. That makes perfect sense. I have a copy of the photo of all the men walking up towards the bridge on their way to work.
