The Sprinter Lighttrain or SLT is an Electric Multiple Unit (EMU) train type operated by the Nederlandse Spoorwegen in the Netherlands.

The SLT is designed to replace the Mat '64 trains from the 1960s and 1970s, and to allow the double-decker NS DD-AR carriages from the 1990s to be refurbished/converted into self-propelling EMUs and transferred to longer, skip-stop Intercity services.

The trains are based on the DB Class 425 design, but adapted to meet the demands of NS and the Dutch railway network.

The SLT is primarily for the Randstad area, around the four main cities (Amsterdam, Utrecht, The Hague and Rotterdam).

They are used on stoptrein stopping services, designed for routes where stations are close together and for this they feature many wide doors and fast acceleration.

In December 2010 more than 2/3 of the SLT's failed after snowfall, leaving the NS to revert to the old trains that had recently been stored out of services.
