Mechanical transmissions are more efficient than hydraulic and diesel electric ones. The lower ratios also give the trains better acceleration from start with lower engine RPM - less noise at stations. Only drawback is a bit more maintenance, I think. | |

So based on what I have gathered, the prime movers will have ecus with can buss connections, and there will be a control module in each of the cars that has controls. The can buss connects all the cars and controllers, which talk to the ecus. So the "go faster" lever is a polite request relayed to the master controller, which decides how to handle the request and issues commands to the ecus over the buss. The systems appear to not be plug and play. Each new design needs new software. | |
