| Cuban Sugar 1, manufactured by Porter as a compressed air locomotive for use in mines or areas where a fire in the firebox would pose a hazard. Cuban Sugar wanted a locomotive that would not cause sugar Cane scraps to ignite. This is the only known standard gage compressed air locomotive in North America. The pressure vessel was charged to 800 PSI, and that gave about 7 operating miles before needing a re-charge. Cuban Sugar ran high pressure pipeline alongside the track so that this locomotive was never far from a recharging point. US Navy 4 in the background was used in the Brooklyn Navy Yard, then spent out the remainder of its operating time at Brooklyn Eastern District Terminal railroad as their number 13 |
