Good luck trying to convince companies to send loads with one truck to the train station, trans-ship to train, and wait for the train to arrive to trans-ship to a truck again. It's much easier to put a truck on the road and have guaranteed delivery in a while (freight trains are slow and probably aren't going often enough).

As for hybrid tractors, semis aren't much going in "stop and go" traffic, so I doubt there's any significant savings to be had in their typical workload. As for saving braking energy, a loaded semi convert during braking much more energy than even a hybrid SUV, so you'd need much bigger generators and batteries. Hybrid is best in stop-and-go traffic, and bad in "long haul" scenarios
