hood size is dictated by internal component requirements

yes

length of the frame for weight reasons.

no.  The bottom plate on the frame is made thicker to get desired weight.

You are describing an FL9, which is 4 feet longer than an FP7/9 and 8 feet longer than a standard F3/7/9.  The six-wheel rear truck was used to improve weight distribution while running on the Park Avenue elevated line into GCT.

EMD FP9 would be the Loco you want for extra space, minus the steam generator. Maine eastern railroad has a couple with the steam gens out and 3rd rail OUT. Nice set up. These are 4 feet longer than your standard "F" unit, and use 6 wheel rear only truck, front is 4 wheel. B-A1A is wheel arrangement. all other F units use B-B.

Just curious. Used to be a flash boiler for steam generation that left space when removed years ago. Wondered if the hood size is dictated by internal component requirements or length of the frame for weight reasons.

There is space between the frame rails to the rear of the diesel engine of most EMD locomotives, I think.  What do you want to put there?  (I wouldn't want to put anything there....)

Is the floor space under a locomotive hood completely filled except for the walkways or could more equipment be put in? Would a 4' by 4' space be available? Thanks.
