Not really. Freight trains do not rely on a storage battery, they need to generate huge volumes of compressed air to operate the braking system, they need a massive amount of air to cool the traction motors and the multi stage current switching system to actually make them useful and efficient over the large operating torque and speed ranges of a train.
So.. they run the diesel when they operate. There is no hybrid mode. There is simply an DC or AC generator connected to the diesel for electrical power take off. This is not the only load consuming PTO power.
Hybrids are the worst of both worlds. You need two drive systems and probably two fully specialized transmissions to make the drive train efficient and you're still screwed for options if any part of the system fails to operate correctly. It's not at all ideal and is not a mini version of a train in any sense.
Plus imagine if you showed up to work driving a train as opposed to showing up driving an electric car. Who's getting a promotion? Not Soyjack, I tell you!

Yes. Sidenote - Here's an interesting vid from the Animagraffs series about diesel electric locos:
