The Railway Museum (Dutch: Het Spoorwegmuseum) in Utrecht is the Dutch National Railway Museum.
It was established in 1927 and since 1954 has been housed in the former Maliebaan station. The museum currently owns a large and varied collection of rolling stock.

Carriage 61 84 89-30 002-9 (Sr 8) for Royal Service of Prins Bernhard preserved at the Het Spoorwegmuseum / Railway Museum in Utecht Maliebaan former Station. July 15th, 2022.
The old Royal Train from 1903, consisting of five wooden carriages, was transported to Germany during the 2nd World War and completely looted, while one carriage was destroyed. Given the age of over 50 years, recovery was no longer an option. In 1948, two steel vehicles with limited resources were fitted out as the new Royal Train. It concerned a former German baggage car, which was fitted out as an Sr 6 escort car. It was equipped with a steam heating system, a diesel engine with generator for the energy supply, a baggage compartment and several sleeping places for accompanying personnel. The second vehicle was the Sr 7, which had been converted more or less provisionally in 1948 from a saloon carriage of the Compagnie International des Wagons Lits (CIWL). In 1953 the SR 8 was added to the train, the salon carriage for Prince Bernhard. In 1956 the Sr 7 was replaced by the Sr 9, the second salon carriage for Queen Juliana.

The Sr 8 and Sr 9 have been in the Railway Museum since 1994. Both carriages originated from 1st/2nd class carriages of the series AB 7521 - 7555 from 1932/'33. They were fitted with a side walkway, end balconies and bellows-folded overpasses. They belonged to the 3rd class coaches C 6401 - 6485, which were previously designed and ordered and consisted of compartment coaches without ramps and bellows.
AB 7522 from 1932 was withdrawn from service in 1952 to be converted into a salon carriage for Prince Bernard by order of the government. In 1953 it was completed as a Sr 8 saloon carriage. The Sr 8 has an office, companions' quarters for the princesses, 2 bedrooms and 2 bathrooms. At the time, the carriage was also specially adapted for the visually impaired princess Marijke (now Princess Christina). The carriage, like the other carriages of the Royal train, was provided with a European admission. They were used as a special train in the Netherlands, but abroad the carriages were coupled to the regular D-trains.
In 1967 the carriage received a new number according to the Uniform Code: 61 84 89-40 002-7.
In 1993, the year it was taken out of service, the number was changed to 61 84 89-30 002-9 after the steam heating installation had been removed. In 1994 the carriage was included in the collection of the Railway Museum.
