In 1902, the NOB was subsumed into the Swiss Federal Railways (SBB CFF FFS), which continued passenger train services on the line until 31 May 1969.

In 1996, these operations were shortened to Rielasingen and on 12 December 2004, freight train services ceased on the entire Etzwilen–Singen railway line.

[7] Heritage trains are operated by the foundation Museumsbahn SEHR & RS (short for Stein am Rhein – Etzwilen – Hemishofen – Ramsen & Rielasingen – Singen), which was founded on 27 January 2006.

Except for the dates on which heritage trains operate, the route section between Etzwilen and Ramsen is open to the use of draisines on Sundays and Swiss holidays from April to October.

During the cold season, members of Museumsbahn SEHR & RS perform maintenance work on the railway infrastructure and the rolling stock.
