Big rigs need to cut fuel consumption up to 23%

Having high fuel efficiency in a vehicle is a great thing for the driver because they can spend less on fuel. Having higher fuel economy on vehicles across the automotive market will reduce the need to import foreign oil and will help to reduce overall pollution as well. The big downside is that the cost of the tech to improve fuel economy is not cheap and that cost will be passed onto the car buyer.

The Obama administration today outlined its Heavy-Duty National Program [PDF] fuel economy standards for heavy-duty vehicles like semis, concrete trucks, dump trucks, and other heavy work trucks. Rather than targeting a specific mile per gallon rating  for the heavy-duty vehicles – like what has been proposed for passenger vehicles -- Obama is going to target a percentage of fuel savings.

The reason for this significant difference in fuel savings is according to the administration imposing a MPG standard on this sort of vehicle would be very confusing considering that the range of categories is wide and the payload and duties in the segment vary widely.

The administration wants a 9% saving in fuel consumption and greenhouse gas emissions for work trucks (fire trucks, garbage trucks, and busses, etc.). Gasoline swilling heavy-duty trucks and vans will need to see a reduction of 10% with diesel versions needing to see a 15% savings. Big rigs have the most stringent cuts at up to 23%.

The regulatory announcement also makes the following claims with regards to recouping the added cost associated with adopting more fuel efficient technologies: 

Using technologies commercially available today, the majority of vehicles will see a payback period of less than one year, while others, especially those with lower annual miles, will experience payback periods of up to two years. For example, an operator of a semi truck can pay for the technology upgrades in under a year, and have net savings up to $73,000 over the truck’s useful life.

The new standards will apply to covered vehicles in the 2014 to 2018 range. The hope is to cut 530 million barrels of oil consumption and $50 billion in fuel costs over the life of the vehicles with the new standards in place.

The cost to meet the new standards on the varying vehicle types are expected to be in the range of hundreds of dollars to thousands of dollars per vehicle.

Yes, these trains are "hybrids".
According to your Wikipedia link they are "series hybrids". Hybrid only in the sense that they use an ICE (as prime mover) and electric motor (for traction).

Why are batteries necessary?
Consider the acceleration profile of a train vs. a truck. Then consider that trying to add batteries to a truck, in order to smooth engine efficiency vs. acceleration needs, would likely add weight to the point of negating desired efficiencies.

Even assuming "hybrid" batteries as espoused on

I don't think the poster you were replying to was attempting to stifle discussion, but rather was decrying increased regulation, unfunded mandates and government intrusion. Get the government out of subsidizing fuels. Let the market decide what to sell.

Diesel-electric locomotives have marvelous technology -- 6000HP yeeha! -- but their weight and cost are optimized for a particular operating regime. I believe it is only a matter of time before trucks and other heavies cross-develop the technology.
