You forgot the batteries.

http://en.wikipedia.org/wiki/Petroleum_electric_hybrid_vehicle#Locomotives

    Diesel-electric locomotives may not always be considered
    hybrids, not having energy storage on board, unless they
    are fed with electricity via a collector for short distances
    (for example, in tunnels with emission limits), in which
    case they are better classified as dual-mode vehicles.
