context_page_description: The InterCity 125 is a diesel-powered passenger train built by British Rail Engineering Limited between 1975 and 1982. Each set is made up of two Class 43 power cars, one at each end and a rake of Mark 3 carriages. The name is derived from its top operational speed of 125 mph. Initially the sets were classified as Classes 253 and 254.
  As of December 2019, InterCity 125s remained in service with Abellio ScotRail, CrossCountry, East Midlands Railway, Great Western Railway and Network Rail.
context_section_description: On the London Midland Region, InterCity 125 trains were introduced later than on the other regions.  They initially appeared on the former Midland Railway route from London St Pancras to Sheffield and Nottingham. Although they were initially not permitted to exceed 100 mph (161 km/h) on any part of the route, they still delivered time savings compared with the loco-hauled trains they replaced.
  The Midland Main Line received a series of speed improvements over the next two decades, until it became possible for HSTs to run at up to 110 mph (177 km/h) on some sections.  An upgrade to the full 125 mph (201 km/h) was proposed by British Rail in the early 1990s, but because of privatisation this did not happen. However line improvements were completed in time for the spring 2014 timetable change, which has permitted 125 mph running on some sections of the line and higher top speeds on others.
  Most long-distance services on this route have been transferred to new Class 222 Meridian diesel-electric multiple units, although many London services from Nottingham still use the InterCity 125, as do all services from London St Pancras to Leeds. Midland Mainline inherited HSTs from BR after privatisation and operated them on its primary services at up to 110 mph.
  43089 also was returned to work on the mainline after being used in an experimental programme conducted by Network Rail and Hitachi. 43072, 43074 was transferred to East Coast in 2012. Currently, 30 are in service with East Midlands Railway. Since December 2013, InterCity 125 sets have been permitted to operate at speeds of up to 125 mph on certain parts of the routes from London St Pancras to Leeds and Nottingham.
