The more hardware, the more higher the failure rates.And you still didn't say how a flexible door system would need to be designed. One way or another, the train would have to know where it is 100% of the time. The only way for it to do so now is by having it told where it starts and which route it will take. Axle tachometers then track progress. This is how the AAS works. Having a door system interconnected to the AAS so that it too knows which doors to open means the AAS is now critical. That's more hardware, more stuff to maintain and more chances of failure for what I'd say is minimal gain (one station that hasn't been used in 40 years). Adding train to wayside capability is no different. The bucking you get now has to do with the way the propulsion system is designed. You'll notice you don't get it on the R142s like you do on the R142As. |
