Hawker Siddeley RTC-85/SP/D were a series of railway coach and diesel multiple units manufactured by Hawker Siddeley Canada for GO Transit, largely based on the H-series subway cars that they built for the Toronto Transit Commission.

Their name was derived as follows: Rapid Transit Coach 85' long Self-Propelled Double-end.^[1]

47 92-seat RTC cars were ordered and delivered to GO Transit in 1967, with 7 of them being built as single-level self-propelled units # D700, D701, D702 to D708 (later renumbered as 9825-9826, 9827-9833), 8 built as unpropelled cab cars (C750 to C757, later 9850 to 9857) and the remaining 32 as regular coaches (4700 to 4731, later 9900 to 9931). With additional cars being built until 1976, the eventual total of the fleet would number 117 cars.^[2] All cars were built at Hawker's Thunder Bay, Ontario plant. In 1975 the self-propelled cars were demotored and used as cab cars.

All cars were withdrawn from service and sold off by GO Transit by 1995 with 6 scrapped and remaining sold to other operators:

23 to Ontario Northland Railway, primarily used on the now-retired (And possible revival) Northlander
92 to Agence métropolitaine de transport (now RTM) (now retired)
11 cars to Pandrol-Jackson Electric Tamper and Equipment Company as crew-cars for rail grinding operations

In 2017, Car 104 was re-purchased and restored by GO Transit to celebrate their 50th anniversary.^[3] The cab car is now displayed at the Toronto Railway Museum in downtown Toronto.^[4]^[5]
