From Wikipedia: "The locomotive had four main engines. Each engine was connected to the gearbox via a hydraulic coupling, which could be filled with oil to transmit power or drained to disconnect that engine from the transmission. ... The engine outputs were combined in pairs by two sets of differential gearing, and the output shafts from these two gearsets were then combined by a third differential gearset to drive the main output shaft." There were also coupling rods between the wheels, though these were later removed.Andrew Kleissnernoreply@blogger.comtag:blogger.com,1999:blog-7432323264902617108.post-81831207015384853962019-10-19T20:59:11.107+01:002019-10-19T20:59:11.107+01:00"The loco was diesel mechanical with hydrauli..."The loco was diesel mechanical with hydraulic transmission.."<br /><br />If it had hydraulic transmission, then it would have been a diesel-hydraulic, so that sentence doesn't seem correct. Most diesel-mechanicals were small shunters.<br /><br />RC169Anonymousnoreply@blogger.com
