Skoda Hybrid Bus, Cropped Version, Marianske Lazne, Karlovarske kraj, Bohemia (CZ), 2011

This is, surprisingly enough, a hybrid bus, for lack of a better term. It can run off of catenary like a trolleybus, or on diesel like a conventional bus. It looks like a Karosa, but it's actually built by Skoda, a traditional trolleybus maker. Here you can see it retracting its trolley pantograph.
