The mail rail part of the museum is
completely separate, just along the road through, what were then, some completely unlabelled doors. We only knew where to go as someone was coming out. Very strange!
So, you need tickets in advance for the mail rail, as the trains are quite small. You travel at the boooked time, but there are other
attractions in this building too, which you see after the ride, the way it's laid out. There are demos of sorting as it was done on
trains for example and an interactive exhibition in the old engineering depot. Again, rather more for the children,
although the equipment there was certainly of interest. The ride itself, taking maybe 20 minutes, was certainly enjoyable, though not if you're
claustrophobic! Lots of nice sound effects and visuals etc. on the journey.
There are more serious things to be done at the Postal Museum, as they have extensive postal records in an archive that can be consulted. It would be wise to book this in advance, which you can do via their website, which includes an extensive index of the material available.
