The NS 1300 was a series of steam locomotives of Nederlandse Spoorwegen and its predecessors Maatschappij tot Exploitatie van Staatsspoorwegen (SS) and Noord-Brabantsch-Duitsche Spoorweg-Maatschappij (NBDS).

After the introduction of the Westinghouse brake, a system whereby the driver could brake all wagons simultaneously, the speed on the railway network could be increased and the SS decided not to expand the series 101–105, but to purchase new, stronger locomotives.

399 onwards, the water capacity of the tenders was increased to 13 m3 by lowering the tank between the frames.

[1] The NS 1326, withdrawn in 1939, was kept for the Spoorwegmuseum and has been returned to its Staatsspoorwegen condition as SS 326.

[1] The mail trains, which had been led via Venlo since 1888, returned in December 1892 to the Boxtel - Wesel, the "German Line".

For this, the NBDS ordered three 1'B express locomotives from Beyer, Peacock & Company of Manchester.
