Le Trolleybus:

Experimentos con iste vehiculo, un combination inter
le tram e le autobus, comenciava in le prime annos
del 20me seculo, principalmente in Germania e Italia,
ma sin ver successo, a causa principalmente de
designos
primitive.

Per exemplo, al linea experimental in Leeds, pro
manco de un interruptor a pedal, le guidator debeva
operar le volante con le dextre mano e le interruptor
rotative typicamente tramviari con le mano sinistre,
un arrangiamento pauco ergonomic, nonne?

Totevia, in Anglaterra in le annos 1920, gratias
a progressos importante in le technologia,
trolleybuses
habeva un grande voga.  Le citates minus grande,
ubi le tramvias era in difficultates economic, trovava
un sollution ideal in iste nove vehiculos que
utilisava
le centrales electric e le masts providite
originalmente pro trams.  Ma iste vehiculos poteva
manovrar se in le traffico sin le restriction de
rails.  Illos anque era quasi silente, e illos
possedeva poteres imponente de acceleration.

Le triumpho del trolleybus pareva complete quando
on construeva in le annos 1930 un enorme systema
in London con un stupende maximo de 1764 vehiculos.
Le voga se propagava al Statos Unite, anque a Germania
e Italia--probabilemente proque ille paises non
possedeva fontes de petroleo.

Hodie il ha nulle retes de trolleybus in Grande
Britannia, ma il ha 16 systemas in China, un total
de 165 in le Union Sovietic, ubi on ha mesmo componite
un canto in laude de illos.


Le annos 1930-1950:

In iste periodo occurreva un triple concurrentia
inter autobuses, trolleybuses, e trams, ma le
resultatos de isto non era identic in omne paises
europee.

In Grande Britannia il habeva, como nos ha mentionate,
un grande proliferation de trolleybuses, ma multe
urbes favoriva le autobus.

In Glasgow, Edinburg, Sunderland, Blackpool,
Liverpool,
Leeds, e Sheffield, le departimentos de transporto
continuava favorir le trams.

On construeva nove lineas que usava nove vehiculos
con carrosseria moderne, sedes confortabile, e motores
e suspension capace de velocitate melior.

Totevia, in Francia, Paris abandonava su trams in
1938, ma grande systemas restava in Marseille e
Lille.

The trolleybus:

Experiments with this vehicle, a hybrid between
the tram and the bus, started in the first years
of the twentieth century, principally in Germany
and Italy, but without real success, primarily because
of their primitive designs.

For example, in an experimental line in Leeds, without
a foot control for the motor, the operator had to
steer with his right hand and manipulate with his
left a series of rotary switches like the ones used
in trams--a rather clumsy arrangement.

Still, in England in the 1920s, thanks to important
technological progress, trolleybuses enjoyed a great
vogue.  Smaller cities, where trams were undergoing
economic difficulties, found an ideal solution in
these new vehicles, which used the central generating
stations and the masts provided originally for trams.
But these vehicles could maneuver in traffic without
the restriction of rails.  They were also almost
silent, and they could accelerate rapidly.

The triumph of the trolleybus seemed complete when
an enormous system was constructed in London in
the 1930s.  The trolleybus vogue spread to the United
States and also to Germany and Italy--probably because
those countries had no sources of petroleum.

Today there are no trolleybus networks in Great
Britain, but there are sixteen systems in China,
a total of 165 in the Soviet Union, where a popular
song was written in praise of them.


The years 1930-1950:

This period saw a three-way competition among buses,
trolleybuses, and trams, but its results were not
identical in all European countries.

In Great Britain, there was, as has been mentioned,
a great proliferation of trolleybuses, but many
cities favored the autobus.

In Glasgow, Edinburg, Sunderland, Blackpool,
Liverpool,
Leeds, and Sheffield, transportation departments
continued to favor trams.

New lines were constructed using new vehicles with
modern suspension, comfortable seats, and motors
and suspension capable of higher speeds.

Still, in France, Paris abandoned its trams in 1938,
but large systems remained in Marseille and Lille.
