Today the line is served throughout by Zurich S-Bahn lines S36, which continues beyond Koblenz to the German town of Waldshut, before the timetable revision in late 2018, the line was served by S41. The midsection of the line, between Bülach and Eglisau also carries Zurich S-Bahn line S9, together with long distance passenger trains between Zurich and Schaffhausen and before the timetable revision in late 2015, it carried Zurich S-Bahn lines S5 and S22. At the Koblenz end of the line, alternate trains on Aargau S-Bahn line S27 from Baden run through to Bad Zurzach.[2][3]

There is also some freight traffic on the line, including through freight between Germany and the Gotthard line over the Bülach to Eglisau section. On the rest of the line, a container terminal is served at Rekingen and a gravel mine at Zweidlen station. In addition there are several trains, principally fuel trains operating to the fuel depot at Glattbrugg station, that route from Basel to Koblenz and then use this route to bypass Zurich.

The line is constructed to standard gauge and is electrified using the Swiss standard of 15 kV  16.7 Hz AC supplied by overhead line. Most of the line is of single track with passing loops, but the busier section between Bülach and Eglisau is double tracked.[4]
