It's been done at spots on Sacramento RT where trains climb on to bridges over UP or over major streets. Batteries (ultracapacitors and flywheel machines have also been used) are located at the substations powering those blocks. With trains running at 15 minute or longer headways, there's often no other train to soak up what a train produces going down off the bridge. Capturing that power and reusing it reduces the peak power demand for trains climbing to the bridge helping to keep electric bills under control. RT, of course, runs light rail on DC, so the conversions aren't a huge deal.
