be hiring one Class 170 per day from Northern to run services on the Manchester/Leeds and Huddersfield local services to allow more Class 185s to be used on other busier services until the new Nova Fleets arrive in 2019. This arrangement ended in May 2019 when Northern’s subleased Class 185 units returned to TPE. Hull Trains Hull Trains began its to Hull services in September 2000 using Turbostars, initially with four sets on short-term lease from Anglia Railways. In 2004, it received four of its own three-car Class 170/3 units, and returned the original units to Anglia. In 2005, following its acquisition by FirstGroup, Hull Trains received four new Class 222/1 Pioneer units and transferred the Turbostars to its sister company First ScotRail. Midland Mainline Midland Mainline (MML) was the first operator to order Turbostars, the first being delivered in November 1998 and entering service in May 1999. The Class 170/1 units were built immediately after the Class 168/0 units were built for Chiltern Railways. MML ordered a fleet of 17 two-car Class 170 units, although the first ten were subsequently made up of three cars each instead. These were numbered 170101–117. The units were introduced on stopping services from London St Pancras to , and . They were also used on summer Saturday services from London to , which later became a year-round service with summer extension to . Class 170s were also used on direct services between London St Pancras and , these services ended upon the replacement of the Class 170s with new Class 222 Meridian units due to weight restrictions on the Derwent Valley line to Matlock. In 2004, Midland Mainline introduced new Class 222 Meridian units, which started to replace the Turbostars. As a result, the fleet was transferred to sister company Central Trains. Ten units (170101–170110) are three-car units, and the remaining seven units (170111–170117) are two-car units. As with the three spot-hire units from Porterbrook, these 17 units had first-class accommodation, which was declassified. Central Trains Central Trains operated a fleet of 53 Class 170 units from various subclasses. In 1999, Central received its first batch of twenty-three two-car Class 170/5 and ten three-car Class 170/6 units. These were used to replace Class 156 units on various longer-distance services. From late 2004, Central also took three Class 170/3 on lease from Porterbrook. Units 170397–8 are three-car units and 170399 is a two-car unit.
