, operates with entire satisfaction, the average voltageof the line during its heaviest hours running from 486 to 510 volts. More recently another ditVicnlt problem has arisen in connectionwith the running of the heavy electric elevated trains over formersteam roads, such as on the Brighton Beach line. These trains willtake from 700 to 800 amperes when starting and an average load of400 atnpercs for four-car trains, when making an average scheduleof 28 miles an hour. This low schedule speed is accounted for by SINGLE RAIL SUSPENSION RAILWAY ATBARMEN. In our issue of last month, page 155, we gave some notes on thenovel single rail suspension railway now building to connect Bar-men, Germany, with Klberfeld and Vohwinkel, and showed linedrawings giving an idea of the construction. Mr. Charles Bonch-sein. United States consul at Barmen, in answer to our request re-cently made a report to the State Department giving additionaldata concerning this undertaking and by courtesy of Mr. Scanlon,

It will thus be seen that thestoppage for any reason of one elevated train makes a considerabledifference in the load carried on one section and consequentlygreatly affects the local voltage. Specially designed boosters could,however, keep these fluctuations well under control, providing wireswere carried to enough points on the line, so that a change of loadwould not greatly affect the pressure over any considerable portionof the line; but if one of the trains stopped and then immediatelystarted again, the current used would run up to 800 amperes anddrop immediately to zero. If there were no trolley cars interspersedbetween the elevated trains and the current for lighting the cars ofthe elevated road were supplied from some source otherthan that used for the trolley cars, a sudden rise in voltage woulddo no harm whatever,
