Platform four started being used on the 25 June 1972 ready for when the new though lines opened on the 2nd May 1973. Most ECML down trains to Leeds and Scotland use platform four

 

Platform 4 was and still is used by up and down Norwich Cambridge and Birmingham Nottingham and Liverpool trains.

 

Freight and passenger trains and light engines can also use platforms 4 both ways.

 

Platform Four is on the eastern edge of a island platform with Platform 5 is on the outer western edge.

 

The buildings on this island platform are of the style of architecture prevalent in the 1960's and 1970's bland and and insipid. But clean and just about fit for there use.

 

These two platforms are linked to the main station by a long foot bridge over the two fast lines. This footbridge was made longer when the new lines with platform 6 and 7 were put in,in 2014.

 

There is also a Post office bridge that was out of bounds in BR days, but is now used for push chairs and the yellow mobility truck that carries wheelchairs and old people over who can't use the stairs, as Peterborough station still had no lifts, right to up till 2014!.
