Chicago Burlington & Quincy Railroad 4-4-2 class P-3-C 2700 at Phildelphia, Pennsylvania, sometime in 1904, photo by the Baldwin Locomotive Works, Chuck Zeiler collection. The following is from the book, Steam Locomotives Of The Burlington Route, by Bernard G. Corbin and William F. Kerka: The P-3-C engines were of the balanced-compound type. Twenty of these were built by Baldwin in 1904 and 1905, and were assigned to the road as 2700-2719. The first ten has 78 inch drivers while the rest were fittted with 74 inch drivers. The locomotives had all four of their cylinders in the same horizontal plane. The high-pressure cylinders were placed between the frame and drove the first pair of drivers through a cranked axle. The outside low-pressure cylinders were coupled to the second pair in the usual manner. Stephenson link motion controlled the steam distribution through piston valves. The inside and outside cranks on the same side were positioned 180 degrees apart so as to neutralize the disturbing forces. The first engine of this class had a one-piece, forged-steel crank axle. The rest had axles built up from nine separate pieces, this type proved more satisfactory. In general appearance, the P-3-C engines were similar to the P-2-C Atlantics except that the cylinders were located further forward to accommodate the inside driving rods to the first axle. This also resulted in a somewhat longer boiler and tube length, 19 feet for the P-3-C compared to 16 feet 9 inches for the P-2-C. Trial runs with the first P-3-C engine, No. 2700, were made in July 1904 between McCook, Nebraska and Akron, Colorado, a distance of 143 miles. Compared to three single-expansion locomotives, a 2-6-2 type and two P-2 Atlantics, engine No. 2700 developed a greater capacity and consumed less fuel and water per horsepower hour than the others. She hauled a twelve-car train, weighing about 580 tons, over the (test) distance in 32 minutes, for an average of 42.26 mph. During the same month, engine No. 2700 made a continuous run from Creston to Chicago in nine hours. The average speed for the 393 mile distance was 43.67 mph. At that time this was regarded as an unusual performance. Number 2700 was rebuilt to class P-6 and renumbered 2583 during 1928. Modifications included replacing the drivers with 69 inch diameter and replacement of the compound cylinders with single-expansion cylinders. Number 2583 was retired and sold for scrap in December 1953. |
