**bostontrainguy**I asked this question on another site and thought I'd ask it here too.

I have always wondered why Talgo doesn't make their coaches longer. The original Turbo Train coaches were approximately 57' long and the present Talgo coaches are only 43' long. A 60 foot coach design would be much more efficient then the 43 foot coach design that they now use. For instance the "new" Wisconsin Talgos are 13 cars long which could maybe be only 9 cars long eliminating the weight and maintenance of additional wheels and connecting mechanicals and support structures. They also could eliminate 8 doors and 4 extra vestibules which saves substantial space. The present design seems like door overkill to me.

To increase capacity with the new Avril model, Talgo has finally maxed out the width to about 10' 5" but the obvious easy solution to extend the length has still not been tried. Why not? Just puzzles me.
