Not sure if this is the right thing to do. There are still other solutions to exploit before saying how the final design will look like.
Right now I'm trying to make a bogey that can fit in the tight space to be at the same height as the platforms and for such I needed to either reduce the diameter of the wheels, or tilt them to find more space for bigger diameters. I tried to go for a Talgo approach so that I could handle the fourth rail clearance with some more freedom between running rails.
Being unexperienced with 3rd and 4rth rail is a bit of a inconvenience for someone who normaly deals with overhead lines.
I'm thinking of a dot matrix indicator for the inside that stands in the door hall. It should tell the destination, next station, time, temperature and which door will open or where is the next available door (in case one door is broken or the platform is too short).
Doors will be of two leafs, each one made of an aluminium framework and either glass or a transparente polymer. The renderings don't clearly show that though.
The interior is still under planning and will depend on if the cars are either the right lenght or too long. I'm thinking about a double longitudinal + transversal seating, with the last more to the ends of the consist.
If a particular car needs to be maintained, each suspended car will have two joints for a dolly to be placed.
Also, somewhere next week I'll be showing footage of the train running on Train Simulator 2014 along the Isle of Wight and London to Brighton lines.
