It is unclear if regenerative braking is used but in principle, it is easily utilized. No fuel is wasted for idling: ≈60–85% of the time for these types of locomotives.

Variant diesel electric locomotive include the Green Goat (GG) and Green Kid (GK) switching/yard engines built by Canada's Railpower Technologies, with lead acid (Pba) batteries and 1000 to 2000 hp electric motors, and a new clean-burning ≈160 hp diesel generator. In the US, General Electric made a locomotive with sodium–nickel chloride (Na-NiCl 2) battery storage.

Already many transport vehicles such as auto-rickshaws and buses run on CNG fuel. CNG is less-polluting alternative for diesel and petrol and is popular as an alternative fuel in India. The first of these trains is set to run on the 81 km long Rewari-Rohtak route. The train has a 1400 hp engine which uses fumigation technology. Indian railway launched one of its kind CNG-Diesel hybrid trains in January 2015. Japan's first hybrid train with significant energy storage is the KiHa E200, with roof-mounted lithium ion batteries. It was an EMD G12 locomotive upgraded with batteries, a 200 kW diesel generator, and four AC motors. The First Hybrid Evaluating locomotive was designed by rail research center Matrai in 1999 and built in 2000. It was tested in Rotterdam, the Netherlands with Railfeeding, a Genesee & Wyoming company.

The new Autorail à grande capacité (AGC or high-capacity railcar) built by the Canadian company Bombardier for service in France is diesel/electric motors, using 1500 or 25000 V on different rail systems.
#Hybrid cars series
Main article: Hybrid train East Japan Railway Company HB-E300 series Both series and parallel setups were used in World War II-era submarines. batteries/ hydraulic accumulators-excepting non-nuclear submarines, one of the oldest production hybrids, running on diesel while surfaced and batteries when submerged. Until recently most heavy vehicles had little secondary energy storage, e.g. With large vehicles, conversion losses decrease and the advantages in distributing power through wires or pipes rather than mechanical elements become more prominent, especially when powering multiple drives-e.g.
#Hybrid cars generator
A diesel/ turbine engine drives an electric generator or hydraulic pump, which powers electric/hydraulic motors-strictly an electric/hydraulic transmission (not a hybrid), unless it can accept power from outside. Hybrid power trains use diesel-electric or turbo-electric to power railway locomotives, buses, heavy goods vehicles, mobile hydraulic machinery, and ships. Heavy vehicle Bus rapid transit of Metz, a diesel-electric hybrid driving system by Van Hool The prototype uses a regular electric bicycle charge port. Active cooling keeps plastic parts from softening.
