I've never been involved with any locomotive builder, but I have been involved in manufacturing for many years. There some very valid questions raised in this forum thread. When it was announced a couple of years ago in Railfan & Railroad that there was a new Alco business coming together it mentioned 3 companies. NRE, FM, and Globe Turbo. This means that this is a joint effort. NRE won't be the only one involved, FM will be quite involved in this effort, since it's their prime movers being used. If you read the article NRE will be the primary contractor for constuction of the locos. FM will bring the prime mover and any auxilaries that they use. Globe is supposed to supply the turbo. I don't know if this is happening as no further word has been heard on this. As far as electicals, still no supplier has been chosen, probably won't be GE. Yes it will be more expensive to build a 2 unit demonstator than a larger order. That's called economy of scale. I'm sure the powers that be at NRE know what they're doing. If I was in charge of this project I would take the C420 platform and update it to current standards. There is nothing wrong with this design, the fact that 30-40 of these locos are still in service is a testimony to a good well designed loco. What it would need is FRA glass, new safety hardwear (updated handrails, ditch lights), redesigned pilot steps, chem toilet, and a fuel tank that has a holding sump for waste oil. I would also place the dynamic brake above the generator/alternator space, just like EMD, GE, and MLW did with their newer designs. When it comes to warranty problems all involved will (should) handle any issues that come along. NRE for the loco stucture, FM with the 251, Globe with the turbo, and whoever for the electricals. If they work well together there shouldn't be any issues if a problem comes along. I'll post further notes in the near future.
