The c2c website stated:  National Express also referred to the c2c route as City to Coast. c2c used the slogan "way2go", but later used the "Making travel simpler" slogan also used by other National Express companies.  c2c operates services on the London, Tilbury and Southend Railway line from London Fenchurch Street to the northern Thames Gateway area of southern Essex, including Grays, Leigh-on-Sea and Southend-on-Sea. The main route from Fenchurch Street to Shoeburyness is , with a fastest timetabled journey time of 58 minutes giving an average speed of 40.7 mph, although the route can be done in 47 minutes, an average speed of 50 mph.

All stations on the c2c route are managed by the company except West Ham and Stratford, which are managed by London Underground, and Barking and Liverpool Street, which are managed by Network Rail. The typical off-peak service per hour consists of 8 trains arriving and departing Fenchurch Street:  In the rush hour there are additional services, with a few services to/from London starting/terminating at Laindon, Pitsea and Leigh-on-Sea. In the morning, one peak-time service does not call at West Ham and Limehouse and one calls at West Ham, missing Limehouse. Other than this, all trains call at West Ham and Limehouse. In the evening, all trains stop at Limehouse and very few miss out West Ham. This was changed in the new December 2015 timetable. On Sundays, the non-stopping service to Shoeburyness does not run. Additionally some early-morning and late-evening weekday services to/from Shoeburyness and Grays terminate at Barking via Rainham. As c2c is mainly a London commuter railway and the typical c2c journey is between 40 and 80 minutes, c2c does not offer first-class seating. Its Class 357s have standard high-density 3+2 seating to meet high demand at peak times, however 17 trains were converted into a "metro" style with 2+2 seating and grab handles. London Underground's District line connects with c2c indirectly at Tower Hill (for Fenchurch Street) and directly at West Ham, Barking and Upminster. Tickets are fully interchangeable between the two operators.
