This is the Festool Guide Rail Tote Bag 466357, it fits two FS 1400/2 and shorter guide rails. I use this bag all the time, it is well made and the rails fit tightly so they don't move around inside the bag.

Here is the outside pocket, it is 32"x8"x1 1/2" made to fit the FS/2 800/2 rails, I use to carry another 55" rail (with the rail sticking out of the up of the pocket).

Two handles and a shoulder strap.

A zipper encloses the rails in the tote.

My only small gripe, I wish it held more rails.
