Zutphen is home to several well-known schools for secondary education on all levels. These include the "Het Stedelijk" (Dalton plan education and bilingual education), "Baudartius College", "Vrije School Zutphen", (a "Vrije School" being a Waldorf School) and "Isendoorn College" (with bilingual education,located in Warnsveld). Students from a wide area around Zutphen learn at these schools. Zutphen railway station is an important regional railway centre. The main electrified lines, to Deventer and Zwolle in the north, and to Arnhem and Nijmegen in the south, are run by the national railway company Nederlandse Spoorwegen (NS). The secondary lines to Winterswijk and Apeldoorn are operated by Arriva. The secondary line to Hengelo is operated by Blauwnet (a division of Syntus). The regional rail service is run by a special subsidiary of the NS. All secondary lines run diesel trains. Zutphen's old station building (1863), upgraded in 1875, was partly destroyed during World War II. In the early 1950s a modern new station was built, a typical post-war building with concrete as its main material. However, in October 2007 the station building was designated as a State Monument. In 2006 and 2007, the area surrounding the railway station was completely renovated: a new bus terminal and an underground bicycle parking lot were constructed, and the main road leading from the railway station to the town centre was turned into a road for pedestrians and cyclists only. Zutphen lies 10 kilometers south of the A1 motorway, which can be entered where it passes Deventer. From there the A1 leads East to Hengelo and West past Apeldoorn to Amsterdam.

Almost all buses in and around Zutphen are operated by Arriva. There are three internal city bus lines, and regional lines to Doetinchem, Deventer, Almen-Laren and Vorden.
