axis. The floor had a carpet. A photo survives with the annotation that there was seating for 72 persons. There was absolutely no provision for standing passengers -there was nothing for them to hold on to. Tender The tender was a completely separate vehicle from the locomotive, only connected by the coupling, as discernible in posed photographs. Not described are the arrangements for the fireman to obtain coal for the locomotive's firebox without risking a fall into the street below. This vehicle was in the same style as the passenger coach, but without end platforms and shorter, at 24.5 feet (7.5 metres). It had the same two rows of windows on each side, but six in each row. Inside was a water tank, a bunker for the coal and "additional room for other purposes". The possibility of parcels traffic was not plainly stated. Locomotive The locomotive also was in the same cylindrical style, with a floor 29.25 by 7.5 feet (8.9 by 2.3 metres) and having similar fenestration, with seven windows in each lower row. The upper window rows, however, were interrupted by a glazed turret which was the engineer's cab and so had five windows each. For the experimental train this cab only gave a view forwards and to the sides, but drawings of hypothetical trains in service show the cab to have a 360 degree view. Turning engines and marshalling trains to have the locomotive in front would have been very challenging to the system (the experimental line had no turntable), and running in reverse half the time would have been desirable. The front of the locomotive had a large circular door in plate glass panels without protection, and was fronted by an open access platform. There was no cowcatcher. The two locomotive trucks were close together, but otherwise were of the same design as those of the other vehicle. Between them was a pair of gripper driving wheels, similar to the truck gripper wheels but larger at 44.6 inches (113 cm) in diameter. They had vertical steel (not iron) axles six inches (15 cm) thick. Each wheel had its own driving mechanism, fed from a single boiler. The following is the Scientic American description of the locomotive specifications: The boiler was of the locomotive type (that is, a fire-tube boiler), 60 inches (152 cm) in diameter and 15 feet 94.6 metres) in length. It was placed over
