City Regional rolling stock) was an electric multiple unit (EMU) train type that was operated by the Dutch railway company Nederlandse Spoorwegen.

The SGM trains had fast acceleration as distances between stations were short, so they needed to be able to speed up and brake quickly.

NS also did consider importing the Paris RER MS 61 train model from France, which was cheaper (per 3-car MS-61 unit as compared to a 2-car SGM unit) than developing the SGM from scratch, however, it was for various reasons deemed unsuitable for the Dutch rail network.

These were to be used on the Zoetermeer Stadslijn and so did not feature first class, a toilet or a gangway between each coach.

2014 and 2015 were built with different electric traction, but their trial was unsuccessful and so the units were stored for many years, until 2000 when they were fitted with Insulated-gate bipolar transistor.

In 1983 2036 – 2080 were strengthened up to three-car units, with the middle coach featuring a first class section.

During their rebuilding, it was attempted to make the entry and exit faster and to increase the capacity in the train.

In 1997 all the two-car units (2001–2015, 2021–2035) were named Stadspendels and operated on the Zoetermeer Stadslijn and the Hofpleinlijn.

The livery was changed to fully yellow, including the doors, and without adverts.

The trains are made for one man operation and for this had mirrors fitted, so the driver could see the platform.

Between November 1994 and April 1995 unit 2008 was converted specially for operation of a night service on the Zoetermeer Stadslijn.

The service was not a success, largely due to the lack of a toilet on board.

[citation needed] From the summer of 2003 until late 2006, all the three-car Sprinters (2836–2895) were modernised by Bombardier Transportation in Randers, Denmark.

Instead, the last train was visible to the general public in the Dutch Railway Museum between December 2022 and July 2023.
