The greatest difficulty he encountered in its construction arose from
the opposition of landowners, mostly small peasant proprietors, who
were anxious to make advantageous terms before they would hear of the
rail passing through their lands. Until he had concluded two hundred
separate contracts, by most of which the peasants benefited, his
platelayers could not get to work. Apart from this opposition the
conditions were not favourable. He was obliged to bridge no less than
ten roads; and the contour of the country necessitated steep
gradients, sharp curves, long cuttings and embankments, the last of
which, owing to a wet summer, could not be trusted to stand quite
firm. The track was doubled for three miles, passing at each end round
a curve of 1600 feet radius.
The rail ran about four feet above the track on trestles bolted down
to steel sleepers resting on ordinary ballast. The carriage--Mr. Behr
used but one on this line--weighed 68 tons, was 59 feet long and 11
feet wide, and could accommodate one hundred persons. It was
handsomely fitted up, and had specially-shaped seats which neutralised
the effect of rounding curves, and ended fore and aft in a point, to
overcome the wind-resistance in front and the air-suction behind.
Sixteen pairs of wheels on the under side of the carriage engaged with
the two pairs of guide rails flanking the trestles, and eight large
double-flanged wheels, 4-1/2 feet in diameter, carried the weight of
the vehicle. The inner four of these wheels were driven by as many
powerful electric motors contained, along with the guiding mechanism,
in the lower part of the car. The motors picked up current from the
centre rail and from another steel rail laid along the sleepers on
porcelain insulators.
The top speed attained was about ninety miles an hour. On the close of
the Exhibition special experiments were made at the request of the
Belgian, French, and Russian Governments, with results that proved
that the Behr system deserved a trial on a much larger scale.
The engineer accordingly approached the British Government with a Bill
for the construction of a high-speed line between Liverpool and
Manchester. A Committee of the House of Commons rejected the Bill on
representations of the Salford Corporation. The Committee had to
admit, nevertheless, that the evidence called was mainly in favour of
the system; and, the plans of the rail having been altered to meet
certain objections, Parliamentary consent was obtained to commence
operations when the necessary capital had been subscribed. In a few
years the great seaport and the great cotton town will probably be
within a few minutes’ run of each other.
A question that naturally arises in the mind of the reader is this:
could the cars, when travelling at 110 miles an hour, be arrested
quickly enough to avoid an accident if anything got on the line?
