Returns for dIesel electric and electric looomotlves represent the number of locomotives, i.e. any combination of looomotlve unlit operated under a single control at the close of each month.
* Cumaulative figures shown in this statement represent averages of the number of units of equipment reported at the close of each month within the cumulative period.
The averages are computed for eaoh railway separately and then totaled.
