Broader than Broad

It is unclear as to how it was proposed to produce a coach body which combined adequate structural strength and lightness. Great reliance was to be placed on the multiple-unit train, so familiar to Europeans today, both electric and diesel powered.

Typically, these would have been made up of five or eight 41 metre long double-deck vehicles. Total seating could have been for up to 2067 passengers, and included, with variations, might have been restaurant cars, bars and observation saloons, hairdressers, shower rooms and other specialist accommodations. Naturally, too, sleeping car trains were proposed. Locomotive-hauled trains generally would have been made up in the same way, but often featuring the 224 seat, streamlined observation car visible in Fig 12; at the rear, there was an upper level viewing gallery and lower level lounge/buffet.

Turning now to some sample locomotives, Fig 7 illustrates Henschel's Diagram 106 proposal for a 17500 hp 3-Fo-1+1-Fo-3 freight type, steam powered, with 24 cylinders arranged one pair to each of twelve axles (at left there is another unfulfilled project, having the same form of drive, but to standard gauge and intended for a trans-Saharan railway). Not covered here are the ten main line diesel and nine of the ten electric locomotives. Surprisingly, steam, not diesel power was proposed for yard work, and Fig 8 pictures the DRG Berlin's enormous rigid-frame 1-C-C-1 Diagram 97 3360 hp 25 atm (367.5 psi) fireless, and beyond it the slightly larger Diagram 98, which shared the same chassis but within its pressure vessel contained a small coal-fired boiler in order that it could be self-charging.
