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.

Postal Unit NS P 8502 of the type Pec, serie P 8501 - 8506, built in 1938 by Werkspoor, Zulien, at the Het Spoorwegmuseum / Railway Museum in Utecht Maliebaan former Station. July 15th, 2022.

Obviously this is not a train set, but in order to be able to accommodate the postal carriage in the group 'Treinstellen' - where it belongs - it is referred to in this overview as 'train set'.

In 1938 the so-called Middennet was electrified. In order to be able to transport mail in the streamlined trains, six matching streamlined postal carriages, series P 8501 - 8506, were put into service. They were all equipped with automatic Scharfenberg couplings to be able to run with the electric trains of the Central Network. In addition, the couplings were equipped with a folding attachment to also be able to drive between or behind the diesel-electric trains, which were equipped with automatic Unirop couplings. A 'bite' was taken from the nose to make room for the folded attachment.
Between 1940 and 1950, the series was expanded with 30 streamlined postal carriages with only Scharfenberg couplings, because the diesel-electric trains had also received these in the meantime.
In 1950 all coaches were grouped into one series: 901 - 936. P 8502 became 902 (without 'P').

In 1972 a number collision threatened with the new Plan V10 trainsets (889 - 920), which caused the numbers of the postal coaches to be increased by 1000. The 902 then became 1902.

The STIBANS ensured that the 1902 was preserved after its decommissioning in 1979, and that it ended up in the Railway Museum after a facelift. In 2007 the carriage received an extensive paint job, during which it was returned to its 1938 condition, with the original number P 8502.
