ade from Lecco to Bellano, and vice versa.I hi average watt consumption of the train measured on thetrolley line was 30.2 watt-hours per ton-kilometer. I he number ol trains simultaneously on the Hue is very lim-ited, and normally there are not more than five to six duringthe busiest hour of the service. In the morning and in theevening there are even less. It is not to be wondered there-fore that the maximum load peak in the central station is aboutthree times as much as the average load for the whole day. JOURNAL. 201 TIM-: ELECTRIC SERVICE ON THE VALTELLINA LINEDuring the last periods of steam traction the daily number oftrain-kilometers on the whole system were 1104, or 686 train-miles: with electric traction they amount to 1998 train-kilo-meters, or 1242 train-miles. For the fiscal year ending June30, 1904, the entire mileage made by the twelve electric vehi-cles (ten motor cars and two freight locomotives) was 678,109km, or 421,447 miles. Therefore one electric vehicle performed

on the average 56,509 km. or 35,120 miles. That is a very-large amount compared with the normal performances of steamlocomotives, especially if one takes into consideration thatduring this period the motor cars were taken out of the servicefor changing the car bearings, two of them having been with-drawn from the service for repairs for several months on ac-count of a collision. The ordinary performance of a steamlocomotive on the lines of the Adriatic Railway is not morethan 27,720 km, or 17,213 miles, per annum. The first years of the electric service proved that also withthree-phase traction it is possible to make up time in cases ofretardation. For that purpose several means are available: (1) The time-table is not worked out for the quickest pos-sible run. a small reserve of time being left between two sta-tions which can be utilized. (2) The motorman does not brake from the highest speed,but the train coasts when approaching the station. By shorten-ing the coast it is possible t
