NS 3737 was on 12 June 1999 guest at the ZLSM in Simpelveld, a steam railway in the very southern tip of the Netherlands. Founded in 1994, the ZLSM has earned a good reputation with their Swedisch (!) locos, a beautiful scenic ride and a diversity of open days like Thomas the Tank Engine (October), Diesel days, the Great Steam Days that mostly take place in July and most of all the Pentecost, when the entire ZLSM network (from Valkenburg to Vetschau near Aachen) is open to public.
