However, no record can be found of the extent or exact nature of the damage. The shops and a number of cars were burned so it is reasonable to assume that the cab and other wooden parts of the locomotive were damaged. One unverified report in the files of the Pennsylvania Railroad states that part of the roof and brick wall fell on the _Pioneer_ during the fire causing considerable damage. In June 1864 the Chambersburg shops were again burned by the Confederates, but on this occasion the railroad managed to remove all its locomotives before the raid. During the Civil War, the Cumberland Valley Railroad was obliged to operate longer passenger trains to satisfy the enlarged traffic. The _Pioneer_ and its sister single-axle engines were found too light for these trains and were used only on work and special trains. Reference to table 1 will show that the mileage of the _Pioneer_ fell off sharply for the years 1860-1865. TABLE 1.--YEARLY MILEAGE OF THE PIONEER (From Annual Reports of the Cumberland Valley Railroad) _Year_: _Miles_ 1852 3,182[a] 1853 20,722[b] 1854 18,087 1855 14,151 1856 20,998 1857 22,779 1858 29,094 1859 29,571 1860 4,824 1861 4,346 1862 ([c]) 1863 5,339 1864 224 1865 2,215 1866 20,546 1867 5,709 1868 13,626 1869 1,372 1870 ... 1871 2,102 1872 4,002 1873 3,721 1874 3,466 1875 636 1876 870 1877 406 1878 4,433 1879 ... 1880 8,306 1881 ([d]) --------- Total 244,727[e] FOOTNOTES TO TABLE 1: [a] Mileage 1852 for January to September (no record of mileage recorded in Annual Reports previous to 1852). [b] 15,000 to 20,000 miles per year was considered very high mileage for a locomotive of the 1850's. [c] No mileage reported for any engines due to fire. [d] Not listed on roster. [e] The Pennsylvania Railroad claims a total mileage of 255,675. This may be accounted for by records of mileages for 1862, 1870, and 1879.
