The NS 7600 was a series of tank engines of the Dutch Railways (NS) and its predecessor Hollandsche IJzeren Spoorweg-Maatschappij (HSM) and Haarlem-Zandvoort Spoorweg Maatschappij (HZSM).

In addition to the numbers 1–4, the locomotives carried the names Haarlem, Overveen, Zandvoort and Rudolph Sulzbach.

After the operation of this railway was transferred to the HSM on June 1 1889, the locomotives remained the property of the HZSM.

In 1903, the locomotives were sold to the Ahaus-Enscheder Eisenbahn Gesellschaft, but remained in service with the HSM.

When the fleets of the HSM and the SS was merged in 1921, the three remaining locomotives of this series were given the NS numbers 7601–7603.
