Lionel 313M-1 Postwar Bascule Bridge Motor - Above you will find a single view stock picture of 313M-1 motor as used by Lionel in their postwar spring driven 313 Bascule Bridge. Some of the motors we have are brand new and some appear to have been recovered from incomplete manufacturing units. In all cases, we have taken them apart to check everything from the armature and windings, right down to the bearings and brushes. When we are finished, they are test run, checked against Lionel's specifications and made ready for your installation. Tired of spending top dollar for junk recovered from run out engines and accessories? Tired of reading "It runs good" only to find out you need to put more money into it? Our motors operate properly and require nothing from you but installation - we guarantee it!
