A very badly drawn map of Plymouth train station.
The environment of the Plymouth train station is a busy one - people move in different directions, and sometimes with cumbersome luggage. It is an area where one must be mindful of others, as the area is small and confined and usually packed with people who are in a hurry.
To the left of the entrance there is an electronic ticket machine, and a traditional ticket office. Most people, including myself, usually go straight to the machine. The machines are useful if you are in a hurry and there is a queue for the main booth, but they are also the only place where you can collect pre-paid tickets - there are often queues for the machines as well as the booth, possibly for this reason.
Opposite the main entrance, there is a WH Smiths, and to the shops right, the barriers to the platforms. On the right of the entrance, there is a small waiting area with seats, and to the front of that area (adjacent to the ticket barriers) there is a Spar.
In front of the seating area and Spar, there are a couple of monitors displaying train information. I found these hard to read, and there were always people crowded around them.
This area of the station is somewhat circular - wherever you stand, you can see the other main attractions (seating, Spar, WH Smiths, Ticket offices, and exit). The main source of natural daylight comes from the entrance, which is mostly large glass doors and windows. The room is fairly light, which may cause trouble with projection equipment.
The area goes between being fairly quiet, and extremely busy and noisy.
This image is of the ceiling of the train station. This is the area where the dome would be.
