Why buy more deck chairs for the Titanic when the concept as a whole is clearly flawwed?I don't know that you've made out THAT case. True, EMUs in our area have MDBF that's an order of magnitude better than the LIRR and MNR dual mode locomotives, but that's not to say, of necessity, that ANY dual mode locomotive would have similar reliability issues. There's one other railroad in our area - Amtrak - that I haven't seen any numbers from, which runs the P32DMs. But as for a conceptual demonstration that the dual mode concept in the abstract as a diesel/third rail vehicle is doomed, I haven't seen that case made yet; all that I've seen is that MNR and LIRR haven't successfully instantiated the concept. Just because two cooks bake a crappy Black Forest Cake doesn't mean that no cook could possibly do much better. Not that you CAN't make out your case about the flawed concept - maybe you can - but you haven't yet done THAT. it's going to require a much stronger showing, which is also made difficult by the fact of how many railroads in the US run these kind of locomotives, right? |
