This saloon is made up of two separate first/third class vestibules and was favoured by the railway directors to carry out inspections of the line, notably to host visiting dignitaries; it was supplied at the same time as F.35 in 1905 from the Metropolitan Carriage & Wagon Co., of Saltley Works in Birmingham.

Both of these two saloons were composites, being split to include a larger first class area, which is retained by F.36 today.  Accordingly, they are slightly longer than the first batch F.29-F.32 which arrived earlier in that same year which were all thirds vehicles.  They are the only series of carriages to survive in their entirety, though all others are heavily modified.

It was not until 1963 that it gained its royal moniker by which it remains known, when it was used to carry the H.M. Queen Elizabeth The Queen Mother between Douglas Station and Braddan Station to attend an open air church service on a special train hauled by No.11 Maitland.

2nd August 1972 saw a larger group of royals travel in it between Castletown and Douglas, for which is was repainted.  In addition to the Queen and Duke Of Edinburgh, Princess Anne and Prince Andrew travelled while Prince Edward stayed on board Britannia with chicken pox and missed the journey.

Again in use in millennium year 1979. King Olaf V of Norway boarded a train at Port St. Mary bound for Douglas Station during a Tynwald Day visit.  The last use by royalty was 1993 when it was removed from the museum especially and used to transport the Duchess Of Kent the length of the line in September. 

It then spent some time out of the museum as part of the Year Of Railways celebrations.  Returning to the museum at the close of the 1993 season, it remained until this exhibition hall was refurbished in 1998-1999.  The saloon was again removed and stored at Douglas Station, returning the next year and remained until the summer of 2022  when trackwork was re-laid in the hall.

After a spell stored in the carriage shed at Port Erin Station it was returned to the main exhibition hall of the railway museum in early 2023 but later replaced and stored in the carriage shed, returning to the workshops in October 2023 when work commenced on remedial panelling replacement.

This was followed by a full repaint retaining its livery first applied in 1972, colour-matched to appear exactly the same as its previous appearance.  All first class seating was reupholstered at this time and much attention given to fixings and furnishings; it returned to the museum in October 2025.
