Lionel 313 BASCULE BRIDGE
C
ongratulations on your purchase of the Lionel 313 bascule bridge. This classic Lionel
accessory has all the terrific action—and traditional quality—of the 1940-50 original. The
illuminated bascule bridge is made of die-cast metal and stamped steel construction and fea-
tures a powerful DC motor for years of reliable operation.
The bascule bridge can be placed in any Lionel O or O-27 three-rail layout, using the frame
provided and is designed to operate at 12-18 volts alternating current.
W
hen properly installed on your layout, activation of the bridge
causes the span to raise to approximately 45°. At the same time,
power to the insulated block leading in and out of the bridge is
removed automatically, to prevent trains from crossing the bridge
while in operation. A second activation lowers the bridge span and
reconnects the power to the insulated block allowing trains to proceed
safely across the bridge. In conventional layouts, the reversing unit
must be locked in forward for automatic train restart. In command
mode, it is necessary to restart your train using your Cab-1 remote. The
bulb inside the shed will light whenever power is on to the bridge. The
flashing warning light atop the bridge will operate only while the
bridge is moving or in the raised position. If the bridge is activated
while a train is on the span, a clutch mechanism is included to prevent
damage to the gearbox. The clutch mechanism consists of interlocking
“crowns” which are spring loaded. These will slip over each other in
event of an overload on the bridge.
The noise the clutch mechanism produces as it slips is loud,
do not be alarmed. No damage has occurred.
DO NOT deliberately activate the clutch. Overuse can lead to
premature wear of the mechanism.

or optimum bridge operation, its location on your layout should
be flat and level. Your bridge is assembled ready for
“O” gauge installation. It displaces two pieces of “O”
gauge straight track. To create the insulated block,
you will need to remove two center rail steel pins at the locations shown
below. There is a large “U” channel/bracket supplied to hold and
align the track at the base of the span(see Page 2 for installation).
