I drive trains for Northern and one of my route is the Harrogate line
Currently the line speed is 60mph, the signalling between Leeds and Harrogate was set up so the could run at 75mph but it was never implemented, also the signalling is a distant signal then a stop signal and some quite long sections between so to run more services would probably need the signaling upgrading, we currently have extra service at rush hour and they often get held at red signals due to this
Platform wise they can run 4 car class 150 as they fit all platforms, 4 car class 158 won’t fit at most due to the carriages been longer than the class 150, the current class 170 units are planned to come off the Harrogate line soon as they are not suited to this slow speed line and are better suited to run at higher speed lines, the only reason they were ever put on the Harrogate line was due to ex Northen directors living in Harrogate and wanting a nice tram on there and not a rattler
