The station building and the nearby freight yard were built from Flonheim sandstone.

Located in the entrance building are the DB travel centre, a car rental and transportation service and a restaurant, which also operates a kiosk facing platform 1.

The buildings are now sold or rented and the open spaces of the freight yard are used for the bus station and a supermarket.

Also to the south was a locomotive depot (Bw Alzey), which was built in 1904, with a 4-stall engine shed, a roundhouse with a turntable and other smaller industrial buildings.

South of the entrance building of Alzey station is a bus station where numerous buses of two Deutsche Bahn-owned bus companies, Omnibusverkehr Rhein-Nahe (ORN) and Busverkehr Rhein-Neckar (BRN), call: ORN routes 424, 425, 426, 428, 441, 442, 444, 446 and 660 and BRN routes 427 and 435 run from Alzey to the Rhenish Hesse region.

In addition, ORN operates routes 421 and 422 as the so-called “city bus lines”, which run through Alzey town.
