This invention relates to railroad motive power
of the turbo-electric type employing steam gen
erating means as a source of power.
'
It is an object of the invention to provide a
novel motive power unit of the above type that is
self-propelled and complete in itself, and is com
paraîtively simple in its construction and arrangeMore particularly the invention contemplates

A As shown in- Figure 2, the motive unit Ill is
provided with an external shell I2> supported on
a frame I-3 which in turn is mounted> on the two
six wheel trucks I4'. A lead truck I5 is associ
ated with the foremost of the two six .wheel
trucks .14.

and about midway between the ends of the mo
rangement of structure- and apparatus such as
the control cab, generator, turbine, ñrebox', boiler,
fuel and water space, in a motive power unit of
the above type, adapted to conserve space but
which nevertheless permits free access to opera
tive parts of the unit and free passage through
the unit.

Another object of the invention is to provide
a motive power system having a high degree of
iiexibility whereby the motive .power `system is
conveniently accommodated Atomeet varied traf-iic requirements. The'novel motive power units
are adapted to be operatedv as single units or in
multiple, permitting the use 'of' the minimum
number of units necessary for the load to be
hauled or the grade of the road traversed.
Another object of the invention. is to increase
the operating radius of< a motive power system

the above referred ‘to '
novel'motil/"ey power units, without stopping vto
take on additional water;

tive unit I0, is> mounted the ísteam generating
plant or bolier I6 andy forward thereof is the
.turbo-electric generating means operablev by
steam from the boiler I6. The turbo-electric
generating mea-'ns comprises the
turbine and gear
set I1 and the generator and exciter i8. All ofr
the wheels I9 ofthe two. six wheel trucks Hipas
wellas all/the wheels 20 of the lead truck I5, are
preferably utilized as drive wheels, and each pair>
of them is provided with a driving motor 2l, the
driving'motors being operable by current from
the turbo-electric means I'I, I B, and being suit
ably supported on the truck frames and suitably
geared to the axles 22 of the wheel trucks.
At'the rear ofthe boiler I6" is a space 23 for
the fireman and to the rear of this is a coal bin
2'4 and a water' tank 25. The engineer’s cab 26,
in which is the control mechanism, is located at
the forward end of the locomotive and a pas'
sageway 21, shown in Figures 3 and 4, extends
from the cab 26 along the’side of the generator
I8,'turbine Il, and the boiler |16 to the iireman’s
space‘23‘ andthence along theiside of thel coal
