This class of light tank engines was delivered with boilers pressed to 8.5 kg/sq cm (120 psi) but were slightly modified in 1884 (see Locobase 7376 for the 1878 specs). The resulting dimensions, weights, and pressures are shown in the specifications.
Four of the class were retired in 1910, but 5 634 lasted until 1924 and 5 632 was withdrawn sometime in 1925-1928.
