See how it fairs inside. Can't be that hard to get TransLink's approval for that kind of an experiment.

The refurbs will also have more thermal gain due to the darker colours used on the outside.

Is there no way for the MarksI trains to be retrofited to have better air circulations? It doesn't even have to be air conditioning, but a roof vent that allows air in at the front of the train and one that lets air out at the back would go a long way towards getting rid of hot air (and smells).

Without some sort of negative consequence for opening windows people will keep doing it. My anecdotal observation from riding the 9 is that 33-50% of the new XDE60 passing by, someone's opened the windows ignoring the label and defeating the purpose of the A/C.

The annoying constant tone thing is what school buses did in the 80's. I'm not sure if they still do it, but it was basically to warn the driver that someone might fall out of the bus if they don't stop.

There should also be some sort of negative consequence for bus drivers letting the coach get too hot, which is the original reason people have learnt to open the windows no matter what. Maybe some sort of temperature/humidity sensor in different areas of the coach which sends annoying warning signals to the driver which passengers can also hear.

Oh god yes. I was in the region a month ago during that nice little span of good weather and the new paint job really did not help with the ventilation issues in the cars. Every time I got on the first thing I did was open all the windows.

Been a while since I investigated but I seem to recall the two squirrel cage fans in each car pull in air from the ceiling vents and exhaust it out the exterior sides of the car. The fans do have a High setting but I rarely ever hear it being used because it has to be manually switched.

I understand that there are safety reasons for dividing the tunnel, but I'm disappointed that they are dividing the tunnel. I was looking forward to view from the front of the train as it traveled through such a large tunnel.

[Mac Write]

The tunnel half easily looks wide enough to have a Canada line train go through it, maybe even a double decker train LOL.

There are safety/areodynamic reasons for this. On the safety side it contains smoke/fire to one half of the tunnel. On the Aerodynamic side the air pressure moves only in one direction. Without the separation it creates additional wind resistance and noise when trains pass each other, and actually damages the trains and parts of the infrastructure. In high-speed trains they actually have to design for preventing tunnel-booms.

Looks like they shifted the guideway to the roadway to reduce encroachment on the greenspace.

Normally, the track entering a station is a straight line for smoother braking, and the track exiting a station is the curved one, since speed would be lower.

Depending on the frequency, most trains will probably be entering directly into the west (westbound) platform, like at Waterfront on the Canada Line. By configuring it like this, they made the more frequent jog over to the west side shorter, and only trains going into temporary storage would have the jog to the right.

That sounds about right. In any case, there's the opposite set of switches just south, meaning the operation can be easily reversed if need be.

[officedweller]

That makes sense - I guess they aren't thinking too much of operation after extension.

That station would've been so awesome for me 14 years ago.

Oooh that would have been awesome for the entire Lower Mainland 14 years ago...

Government keeps Evergreen Line costs, overruns shrouded in secrecy

The BC Liberal government is refusing to show how much it has spent so far on the Evergreen Line.

The Millennium Line SkyTrain extension to Coquitlam and Port Moody was budgeted at $1.43 billion, but the Ministry of Transportation and Infrastructure censored the spending breakdown from the April financial summary, which was released last week under Freedom of Information.

Later this century when Evergreen is extended eastwards to Maple Ridge and becomes the Lougheed - Coquitlam - Maple Ridge 'mainline', the segment up Pinetree will become a convenient way to short-turn trains and send them back to Lougheed.

[officedweller]

Yeah, I'm in the "where's that going to extend to"? camp as to future extensions.

when are you testing thru the tunnel?

Now that's what I wanna hera!

I've thought that the Lafarge-Douglas would remain a terminal.

I'm not sure if there are plans to extend it up Pinetree to Westwood Plateau, or somehow extending eastwards over to somewhere on Coast Meridian.

I think Westwood Plateau doesn't (and won't) have the population density to support an extension up Pinetree, and any stations east of the river are easier done as part of the next extension along the CPR tracks to Maple Ridge (or Mission)
