The Manitou & Pike's Peak
Railway. Engineering News, December
7, 1889
The Manitou & Pike's Peak Ry., in Colorado, which is to
be built up the mountain of Pike's Peak, and the grading of which
was commenced two months ago, will be built on the Abt rackrail
system, and will be the first application of this -system in America.
The first surveys for the road were made in November and December
of 1888 by Mr. F.E. Baxter, C.E., of Colorado Springs, Col., who
located the line which will be very closely followed in the present
construction. Mr. R.E. Briggs, of Denver, then Chief Engineer
of the Denver & Rio Grande R. R., was afterwards appointed
Chief Engineer, with Mr. T.F. Richardson in charge of the final
surveys and of the construction of the road. Major John Hulbert,
of Manitou Springs, is President of the company; among the directors
are Mr. Cable, President of the Chicago, Rock Island & Pacific
R. R., Mr. Z.G. Simmons, of Kenosha, Wis., and others. Mr. Simmons
has also taken the entire contract for the construction and equipment
of the road. Mr. W. Hildenbrand, C.E., of New York, who is the
representative of the Abt system, is Consulting Engineer ; he
will furnish the rackrail and be in charge of the laying of the
same. The order for the rack-rail has been placed with the, Johnson
Co., of Johnstown, Pa.; the Baldwin Locomotive Works, of Philadelphia,
Pa., have an order for three locomotives, and the Wason Mfg. Co.,
of Springfield, Mass., has the order for six passenger cars. Lantry
& Sons, of Denver, are the contractors for the grading and
road-bed, and they had four miles graded when the recent heavy
snowfall prevented further work on the upper part of the mountain.
It is intended to open the road for traffic on July 1, 1890.
The length of the road is 8¾ miles, but the track, including
switches and side tracks, will be 9.4 miles long; the total rise
is 7,600 ft., giving an average grade of 16.3 per cent. The maximum
grade is 25 per cent. and the minimum grade 7.6 per cent. The
lower station is 6,600 ft. and the summit 14,200 ft. above sea
level.
The locomotives will weigh about 25 tons in working order,
and the specifications require that each engine shall have sufficient
power to push two loaded passenger cars, weighing from 20 to 21
tons, up the 25 per cent. grade at a speed of three miles per
hour, up the average grade at five miles, and up the, minimum
grade at eight miles per hour. Each locomotive will be provided
with three driving pinions or spur wheels working in the rack
rail, and will have ample brake power to stop and hold the train
on the down trip. In addition to this each car will have separate
brakes, enabling it to be stopped independently of the locomotive.
No expense will be spared to make the equipment first-class in
every respect. The cars are to be arranged for 50 seats, will
be handsomely finished and comfortable to ride in. They will be
carried on four wheels, which will be loose on the axles; the
object of this is to make the cars as light as possible, which
is an important item in the construction as well as in the operating
expenses of a rack railway.
The rack-rail will consist of two bars, 4½ ins. deep and
varying in thickness from seven-eighths in. to 1¼ in. according
to the grade. It will be of mild steel of the highest quality
as to strength and ductility. The chairs carrying the bats will
be of annealed cast steel. The splice bars and bolts will be of
best quality iron. To prevent creeping down hill, the track will
be anchored to about 200 stone or rock anchorages.
The work is to be pushed with vigor, so as to have the road
opened at the appointed time, and to obtain the revenues of the
next season. It is estimated that the road will carry an average
of 300 passengers per day, which will give very good returns on
the outlay of the capital for the construction of the road.
