Good responses on qualifying the three items I tossed out there folks. Within the RR community there is a tremendous amount of disconnect concerning what those terms mean.
My experience has indicayed that any work to be performed needs to be spelled out in very specific and minute detail. The term boiler plate comes to mind.
Often times what you think you are receiving for funds expended and what the vendor feels they are obligated to are vastly different.
It goes without saying that the higher the level of renewal and staying close to OEM minimal clearances leads to a more expensive product. my position is if the money has to be spent spend it once not twice.
Another peculiar term in the industry is running take out (RTO) that in itself is an oxymoron as it relates to what condition the equipment that is being purchased. Taken out runiing, running good, running poorly...
You get the picture.
Locomotive diesels are not slow speed in the true sense nor are they considered medium speed such 16-149 twin tubo Detroits. They fall somewhere in between.
A remanufacture (speaking of loco diesels here) will consist of all new components other than the block, pan, crankshaft and miscellaneous castings.
A rebuild will reuse other components such as connecting rods/gears, shafts, blowers, turbo chargers and other items that have been reworked to OEM specs. New items will include liners/eads/pistons/rings/bearings/bushings
An overhaul will use reconditioned liners/heads/pistons with new rings, bearings, gaskets. Usually an inframe diesel overhaul is where this would take place.
Cheers.
