this is a very old video. That design of bus hasnt been used by King County Metro for at least 10 years. The buses that do run in the tunnel now use diesel (not their trolly poles), and there is also now light rail sharing the tunnel with the buses, one of the very few tunnels in the world to share trains and buses in one tunnel.

It is already working in CIS and Central European countries on a daily base for a decades (30-40 y.) ... no wonder just have a look in Batislava or another one how it works :) !! What a New World - America ... Good luck :) !

it's like a bus stuck in a wheelchair :D Hermaphrodite is the perfect word. I don't think other normal busses have a good impression on theese freaks especially the older ones :D

Wow I'm struggling to understand how this makes sense.Maybey it was a legal loophole or something?It looks like a bus,it acts like a bus....but it has it's own right of way, a catenary,a wayside signal system and rails.Sheesh maybey I should have stayed in school because this one went way over my head...lol.Nice video,thanks!

its fucking tram not bus

Hybrid. Awesome, but odd.

Yes. LOL.

i love seattle

its beautiful, i like it, because its different

so its a bus or a train lol? :D

NICE !!!!

Was this once used for streetcars? or now multipurpose? not that i dislike trolley buses, but seeing deserted streetcar/LRT tracks is sad.

Boy does this video bring back memories. I drive this tunnel 4 nights a week. This tunnel used to close at 8 p.m. weeknights and weekends, now open till 1a.m. and weekends. No more electic buses (thank god) now only hybrid buses. We now share the tube with the new light rail train.

Seattle seems even more sensible than i imagined. Cute and Co-operative.

Amazing. I've never seen a public transport system like this befoe. I want to go to SEA.

are these able to drive around normal streets as well? or are they electric only?

here in Bratislava - Slovakia we have duobuses - that means electric bus, that can drive without electricity. it has diesel generator.

I really like this metro-trolley-disel-bus. This is very unique and original. I have never seen anything like this anywhere !

@dpjaexp It still is, its just used by the light rail now.

Metro - Trolleybus ,o)

Also, that 'bus tunnel' under Harvard Square used to be a streetcar tunnel through which PCC cars ran out to North Cambridge, Watertown, Belmont and Waverly.

As part of the original Big Dig public transit promises, the Silver Line was originally supposed to have been part of the Green Line, and it was supposed to have been trolley service that was to run up Washington Street, all the way into Downtown Boston, following the old elevated Orange Line route all the way from Forest hills. It was supposed to have gone into the (currently disused) tunnels from the old Lenox Street branch, into Boylston Street (the wall rails in the station).

True, this is why we must push our governments with petitions and protests for for CLEANER sources such as SOLAR and WIND or WATER plants.

The electricity has to come from somewhere though, could result in an increase of electricity output from a coal plant for all we know.

You hardly ever see any in cities anymore, just STREETCARS making their comeback INSTEAD for the most part. Electric buses came out in a lot of cities to replace the streetcars with more modernized technology. They should start to replace diesel fuelled buses in some of the SMALLER cities today!
