Forward cross bearer structures 20 and 22 extend transversely of and are secured to the center sill members and the rear legs sill 6 by bolt 120, and an upstanding abutment 119 paral lel with flange 8 at the upper end of the carrier plate. Between the abutment 119 and ilange 88 is arranged a resilient unit comprising a rubber sheet 122 between and bounded to plates 124. This resilient unit is secured between the abutment and ñange 88 by bolts 125 and 126. Another angular stop member having a base 128 of the front sill 12 in advance of forward bolster 16.

Another angular end Two similar traction power plants A (only one of stop member extends vertically inside of mounting plate which is indicated in Figs. 6, 7) are arranged in longitu 96 and one flange 136 is parallel to such plate and an dinal alignment on the longitudinal center line of the other ñange 138 is parallel to end plate 94 of the carrier locomotive power compartment. The space bounded by plate. Flange 136 is secured to plate 96 by bolts 140. the center sill members 6 and bolsters 14 and 16 is divided Between flange 138 and end plate 94 and between flanges by the cross bearer 18 providing two openings of suñ’i 130 and 88’ are arranged resilient units comprised of cient length and width so that the power plants A can kplates 142 and intermediate sheet rubber 144 bonded be mounted therein to place the center of gravity close thereto, the units being secured in such relation by bolts to the underframe and to allow the power plants to be 145 and 146. 2,717,746 3 While the engine mounting just described comprises a 4 member comprising a vertically extending carrier plate mounting plate, a carrier plate, end resilient stop means having an engine bearer on its inner face and an out and vertical movement restriction means that are detach able, they can be assembled as a unitary structure for with the carrier plate having a bearer adapted to rest application to or removal from the center sill member, Gi and also for adjustment lengthwise on the sill. Upon removal of bolts 92, 100, 120 and 132, the mounting units M can be shifted longitudinally to permit the associated engine leg 82 to freely pass thereby in a vertical direction. To dismount the engines A and B, they are jacked up with bolts 92 removed to permit longitudinal movement of the mountings into either engine receiving position or engine removal position. During this operation, the locomotive is preferably located over a pit in which suit able jacks can be arranged for raising and lowering the main engine. The engines are mounted to float on rub ber so that operational vibration will be substantially damped without transmittal to the underframe. The invention may be modified in various respects as will occur to those skilled in the art and the exclusive use of all modifications as come within the scope of the ap pended claims is contemplated. What is claimed is: 1. A mounting for carrying an engine on a frame com prising a vertical carrier plate with a top flange having one end turned down, a mounting plate parallel with the vertical carrier plate and having a bearing extension adapted to be detachably secured on the frame, rubber means between and secured to said plates, an abutment adjacent said downturned flange end adapted to be de tachably secured on the frame, and rubber means se cured to and between said abutment and said downturned end portion of the carrier iiange. 2. A mounting for carrying an engine on a frame member comprising a vertically extending carrier plate having an engine bearer extending from the inner face and an outwardly extending top ñange, a mounting plate parallel to the carrier plate having an intermediate ont wardly extending bearer adapted to be secured on top of the frame member, rubber means between and secured 40 to said plates, a bracket secured to the outer face of the mounting plate above the mounting plate bearer, and means associated with the top flange of the carrier plate and the bracket for snubbing vertical movement of said carrier plate. 3. A mounting for carrying an engine on a frame wardly extending top ñange, a mounting plate parallel on and to be secured on said frame member, said mount ing plate being spaced from said carrier plate top ñange, rubber means between and secured to said plates for floatingly supporting the carrier plate, a bracket on the mounting plate and resilient snubber means between the carrier plate and bracket resisting vertical movement of said carrier plate, the top of the mounting plate serving as a stop for the carrier top flange in the event of failure of the rubber means. 4. The combination of center sill frame members spaced to receive an engine therebetween, a plurality of similar mountings each comprising a vertically extending carrier plate having an inwardly extending engine bearer, a mounting plate having a vertically extending portion parallel with the carrier plate and an outwardly extend ing bearer slidably mounted on the center sill frame members, rubber means between and secured to the paral lel portions of the plates, detachable means for securing the mounting plate bearers to the sills, spacer means between the vertical portions of the mounting plates and the adjacent center sill frame members and a guide rest secured to the bottom of the sills for receiving the bottom of the mounting plates and spacer means.
