Unless you're in Europe, where much of the rail network runs off electricity rather than diesel, in which case regenerative braking would be pretty easy to do.
Sometimes I wonder at US railroads. I see trains hooking on extra diesel locomotives for the trip over Donner Summit, then braking all the way down into Sacramento, when with an electric system and little ingenuity, the downhill train could be providing most of the power to one going uphill.
