Special locomotives are used on the line. These were constructed by the Baldwin Company, of Philadelphia, and include the latest patents in engine building. When standing on a level track they appear to be at a slant of about 8 per cent. When on a mountain road, like that of Pike's Peak, they are approximately level. There are three wheels on each side of the engine, but these are not driving wheels, being merely used to help sustain the weight. The driving wheels operate on the cog rails in the center of the track. The cars also slope, or slant, like the engine. No couplings are used, so that one great element of danger, is avoided. The engine and the cars have each independent cog brakes of almost unlimited power. When traveling three or four miles an hour, the little train, with the locomotive pushing instead of pulling it, can be stopped instantly. When the speed reaches eight or nine miles an hour, stoppage can be effected in less than one revolution of a wheel. Not only is the ride up Pike's Peak a wonderful sensation and a constant reminder of the triumphs of engineering, but it is also a source of continual delight to the lover of the beautiful and awful in nature. About half way up the mountain is a most delightful little hillside retreat, aptly named "The Half-Way House." It is a very comfortable establishment within rustic walls. The pines and firs which surround it add a great charm to the outlook, and the cool mountain breeze is charged with very pleasing odors. Tourists frequently spend a night here and consider the sensation one of the most unique of a long trip. A tourist describing a ride up Pike's Peak by this singular railroad, says:
