  1. King County Metro - Seattle, Washington

    Lots of interesting (to me at least) architectural/technical design info there. Not sure what used radios have to do with any of it.
  2. King County Metro - Seattle, Washington

    Much more technical information on page 242 of this document.
  3. King County Metro - Seattle, Washington

    I found a cache today that included 8199. It was green. So going off the list of 8100 ~ 8116 and 8150 ~ 8199 being green and 8117 ~ 8138 being blue, I'd say there's little chance of there being much else.

    Metro claimed that the floor structure changed from the DE60LFR -> XDE60, and because of that structural change, they were unable to retain the same "open" layout.

    Here's 8122 at the New Flyer facility: And 8166 pulling back in after a short yard test: 8165 as well as several others could be seen inside.

    ST didn't build anything new, they just piggybacked on a system built by a different (non-transit) agency. It's Metro that went all out and built something new, and they didn't really have a choice. If anything, I see ST buying capacity on Metro's system. Neither of the existing systems reach Lynnwood, so who knows what's in store in the next 10 years.

    This is all pretty stupid. For many dozens of years before the tunnel closed, Metro operated on a UHF (450 MHz) conventional analog system. Since ST didn't exist, there was no need for interoperability. The system had expansive coverage throughout King County and beyond, and even had dedicated repeaters in the tunnel. Since its inception, Link has used an 800 MHz trunked system (PSERN). It's the same system used by every police officer, firefighter, and loads of others in King County. When joint operations started in the DSTT, Metro had to install a second radio in every bus that went in to the tunnel. Apparently having train operators and bus operators able to talk to each other prevents crashes (or something like that; probably some sort of rule set out by the FRA). In 2011, Metro replaced their old UHF system with a 700 MHz trunked system. Despite only being 300 MHz apart, the two were nothing like each other and wouldn't be able to use any of the same equipment. The 700 and 800 systems aren't terribly different from each other. From a technical perspective, there is no reason why Metro couldn't have been put on PSERN. However, voice transmissions on transit systems tend to be frequent, long, and drawn out. PSERN didn't have the capacity for that, so Metro had to build their own. Both systems use Motorola radios. Motorola sells radios that will do 700 and 800 in the same radio. I'm 99% positive KCSO Transit PD carries these so they can talk to the PD dispatchers and the Metro coordinators without having to have two radios on their belt. The same could have been done in every tunnel bus. But for reasons of timing (and maybe some systems integration issues) it wasn't. So now every bus that goes in the tunnel bus has to get an extra radio installed, and at the end of joint ops there's going to be a ton of surplus 800 radios.

    I thought there were some changes to the ventilation system at one point that made it a much, much more rare occurrence for a diesel coach to run through the tunnel. So much so that trips could be canceled or rerouted. I've also heard that if a route is inbound on a diesel, they'll run it on the surface and arrange for a coach change before allowing the run to continue outbound.

    They did this before they went in to service: Earlier this year when Metro announced they were buying more I tried to get someone at Metro to say where they'd be adding service. Everyone shied away from the question, and none would admit where they'd be adding more charging stations, and I got the feeling that they'll be staying on Tha Eastside for the time being. Only time will tell.

    Indeed I did.

    Route 8 also has the D60s, though the 8100s are much more common now.
