Just at the end of Middlesbrough station is the signal box. It's a North Eastern C1 box that opened in 1877. It contains an IFS (individual function switch) panel. Once again, it's a shame that the surroundings of the box have been spoilt by the installation of the palisade fencing. I took a photograph of the signal box from a departing train back in 1980, note the white concrete lintel to the right of this photograph.....
