The arrival of the railways from the mid 19th century onwards, created a significant source of employment contributing to the town's growth as a rail hub at the centre of five distinct railway lines. The high speed rail line (HS1 High Speed 1) between London and the Channel Tunnel passes through Ashford's International Railway Station thus linking the town to Paris and other European destinations. The M20 motorway connects Ashford to the Channel Tunnel, the national motorway network (via the M25 Motorway) and to London (via the A20).
