I've been on many metro system around the world and the MKI trains are definitley the noisiest during accelaration and decelaration.

2. During construction of the Millenium Line, a short section of the Expo line guideway was strengthened to accomodate the heavier MKII trains. This section was between Main street and the Home Depot. The horizontal beams had some additional croncrete added to them right where it joins the column. Why was only such a short stretch strengthened? Was that particular stretch actually weaker than the rest of the guideway?

3. MKII trains have air conditioning, yet the windows are openable. Why is that? (I noticed that they have now put stickers on the windows saying to only open them up in emergencies.)

Thanks
The sound comes from the power conversion unit in the MKIs - the MKIIs use a different model of power converter, so no sound.

The part of the elevated guideway that needed strengthening was the "demonstration line" built before the rest of the line was built.

The air conditioning in the MKII cars only takes the temperature down to ambient temperature - the temperature outside the trains - so you can open the windows without straining the air conditioning system.

The skytrain has some of the nicest trains in North America...

Looks like NYC's JFK airport Airtrain.

^ That's cause the NY AirTrain uses the Advanced Rapid Transit system, which is the same as Vancouver's SkyTrain, and Bombardier was contracted to build the cars. Those are the MKII cars, as are the KL Putraline trains. Only, the NY cars come in single unarticulated cars.

KL's Putraline (Kelana Jaya line):

*Line is now run by RAPIDkl and logo has been changed.

those are very very very good looking trains. 9.5/10 in my opinion. if they just had a 3rd, intermediate coach, they'd be an untouchable 10/10. the colors, the shape, the windows, everything is perfect, they just need to be a wee bit longer.

hmmmm.... I've been on MKII trains on a hot day, it seemed alot cooler inside the trains than outside. Most trains on other systems that have air conditioning don't have openable windows, like NY's MKII cars or Toronto's subway. Plus, the windows on Vancouver's MKII trains aren't large enough to escape out of in case of fire. Also, opening a window during a fire on a train may not help, it may make it even worse by allowing more oxygen in.

Anyways, I don't mean to slag the skytrain, it's just an observation. I actually really like the MKII cars, they are such a HUGE improvement over the MKI trains.

ok theres one thing im confused about.

heres a map of the area around Broadway and WCD station:



the millenium line was extended to the vancouver community college this january. it is locaed by the little dot on the map.

red is broadway, where a possible future sky train alignment will go towards arbutus, at least according to wikipedia

green is the completed millenium line. dashed green was work i saw being done on google earth.

the lower green, right above broadway, is where this possible future alignment will be.

if there is work being done/was done done NORTH of broadway, how do they expect to suddenly align it with broadway from VCC station? first of all, unless more work was dune since this satellite picture was taken, the "VCC station" is actually almost half a kilometer away from the main college entrance!!! can someone just explain this to me? i dont see how its possible for the train to go under broadway if the first station is so far north.

That's what I read either in the Buzzer or in the newspaper one time - can't recall where exactly. It could have been one of those complaint columns where reader write in complaining about others - but here the response was that you could open the windows without harming the air conditioning.

It is not actually located by the little dot. The station is now completed and it is along the northern green dotted line.

Yes, the possible future extension will be along broadway. The northern green dotted line in your picture is where Millenium Line currently ends and it will turn south again and rejoin broadway. The next station would be Main St. and Broadway.

The dashed green line along broadway: Yes, work is being done there right now but that is for sewer replacement only.

Quote:

The Millenium line would rejoin broadway roughly where all the green question marks are.


Here is a link to the City of Vancouver website regarding possible extension options. (somewhat old info, but still valid and very interesting) http://www.city.vancouver.bc.ca/engs..._extension.htm

Btw. Why the strong interest in Vancouver transit? Just curious...

Read this fact sheet from the City of Vancouver - this shows where the line will probably go (although the City of Vancouver will not control the route location). The line was diverted north to the False Creek Flats to serve future high tech office space in the area.

dont know if its that special, but i live in almere, a town near to amsterdam holland. and here we have seperate bussinglanes and cycle roads all over the town. its a new age very suburban style living town wich is 30 years old or so. and everything is new and they decided to seperate all types of infrastructure completely, i think its pretty impressive, were ever you live in almere it is max 500 meter to the next bus station and all of them on the seperate bussinglanesystem also the cycling roads are nearly everywhere, i've got no statistics but maybe another dutch forumer does. further is all dutch public transport very well organized, not a real big metro system but for that there's to much 'sprawl' in holland, i think we've got pretty much trainstations per citicen in holland. well thats what i have to say maybe some dutch forummer can show here some pictures.

what he actually means is a third car in the middle of the existing two-car trains.

right. a three-section train. three sections would give it a more massive, "important", "major league" feel.

Three-car trains are possible with extended Canada Line platforms (from 40 metres to 50 metres). Car A: 20 metres; Car C: 10 metres; Car B: 20 metres
