The station has five standard-gauge platforms serving nine tracks and is the central node of the local Stadtbus Winterthur [de] network and regional bus services (e.g. PostBus Switzerland).

All public transport in and around Winterthur is part of the canton of Zürich's integrated fare network ZVV.

[8] Five years after the opening of the provisional building, the first real station was built, under the direction of the architect Jakob Friedrich Wanner, who, together with A. Beck, was responsible for the design.

The builder, Meier, came from Winterthur, and the train shed was built by the firm Benkiser of Pforzheim.

This expansion consisted of an extension to each side of the station building equal to the width of four window bays, in order to create space for new waiting rooms.

These renovations, proposed by the architect Ernst Jung and Otto Bridler, produced a station building in Renaissance style; the Federal Palace of Switzerland served as a template.

In 1980, the station was again extended by two tracks (the current platforms 1 and 2), which were used for the Tösstal line and for postal trains.

As a replacement for the closed structure, a maintenance facility was built at the Oberwinterthur railway station.

Only the lines that serve Wiesendangen and a few villages northeast of Winterthur depart from Oberwinterthur station instead.
