The aim of the game is to complete a simulated journey of the Southern Belle steam passenger train from London Victoria to Brighton while keeping to speed regulations, being careful not to derail when going around curves and completing the journey on time. There are various options available including a demonstration run, where the computer takes control of the locomotive, and a number of challenges such as beating the real record breaking run for that line, set on 26 July 1903 (at 48 minutes 41 seconds).
The graphics were "vector-style", but because of the limitations of the ZX Spectrum and such computers, the graphics were minimal. The framerate was very slow, updating only once per second. This was particularly notable when playing in "Fast" mode, where gameplay could be sped up x5 by pressing the "A" key. Also, the main gameplay screen lacked colour, with most versions being in monochrome. However, the ZX Spectrum version did include a "red" fire. Additionally, there were sections of line where there were no buildings visible in the foreground, leading to criticisms that the game looked as though the countryside had been hit by a nuclear bomb.
The game's demo mode was a high speed run, in homage to British Transport Films's classic London to Brighton in 4 Minutes. The next station/tunnel's name appeared as a totem sign at the top of the screen (just after Gatwick Racecourse, it changed to Three Bridges and the lineside features passed in that section included three bridges).
