The Winterthur–Romanshorn railway, also known in German as the Thurtallinie ("Thur valley line"), is a Swiss railway line and was built as part of the railway between Zürich and Lake Constance (Bodensee). It connects Winterthur with Romanshorn, where it formerly connected to train ferries over Lake Constance. It is the fourth oldest internal railway in Switzerland. Its construction was to be funded by the Zürich-Lake Constance Railway (Zürich-Bodenseebahn), but during the construction the company was merged with the Swiss Northern Railway (Schweizerische Nordbahn) to form the Swiss Northeastern Railway (Schweizerische Nordostbahn, NOB). The Winterthur–Romanshorn railway was opened on 16 May 1855 and the line from Winterthur to Oerlikon was opened on 27 December 1855. Zürich was reached on 26 June 1856 and the two existing NOB lines were connected.

The Lake Constance train ferries on the Romanshorn–Friedrichshafen and Romanshorn–Lindau routes were established to connect with this line.
