TDE Posted September 23, 2009 Report Share Posted September 23, 2009 OK so I give up... this was going to happen. OK so question 1: What's the difference between having two and three searchlight signal heads? I know there's a passive and absolute situation about the placement of the two heads. Question 2: Is there a difference between a (green) (red) (red) signal versus... a (red) (green) (red) or even a (red) (green) (green) Question 3... is there a difference between a slid green signal versus a flashing green signal?

smallspy Posted September 23, 2009 Report Share Posted September 23, 2009 OK so I give up... this was going to happen.OK so question 1: What's the difference between having two and three searchlight signal heads? I know there's a passive and absolute situation about the placement of the two heads. It's all about the placement of the heads. If they are in line, than they are guarding an interlocking or controlled location, and so the signals are absolute. If they are staggered, then they are generally automatics and considered restrictings. As for 2 vs. 3 - that has to do with line/track speed. 3 signal heads are used where the signals are also used to control train speed, mainly in locations with passenger trains. You can find out more about them, and signal indications, in the CROR. Question 3...is there a difference between a slid green signal versus a flashing green signal? Yup - solid green indicates a "proceed" signal, whereas flashing green is a "limited" signal. Dan Link to comment Share on other sites More sharing options...

Or, if they're only going to as far as Port Credit/Mississauga area, or north of Toronto, along the Oakville Sub?

There's CN435 which you can catch usually anytime from 12:00 to 14:00. Comes down the Bala, through the USRC, along the Oakville Sub, making stops at Oakville Yard and Aldershot Yard, I believe it heads out towards Brantford and London afterwards. Anything else along the Oakville from Burlington to Toronto during the day would be a road switcher working out of Oakville Yard or Mimico, making set offs at various industries, such as Petro Canada. Most frieghts bypass the Oakville and Kingston subs using the Halton and York subs. Link to comment Share on other sites More sharing options...

Most frieghts bypass the Oakville and Kingston subs using the Halton and York subs. The roadswitchers that work the Oakville Sub in daylight hours between Toronto and Burlington West are 543 out of Mimico, 553 & 556 out of Oakville Yard, and the night roadswitchers 557 & 552, 552 essentially being a transfer job that takes loaded multi's to Aldershot along with other traffic and build freight blocks for morning trains to lift. Along with 435 (used to be 333 job before cancellation to haul Oakville traffic via downtown) the occasional 332 will run to Oakville Yard to set off Ford multi's before heading downtown and up the Bala to Mac Yard.

M.Wright Posted September 26, 2009 Report Share Posted September 26, 2009 I got a question, though I'll probably find out what the answer is as soon as I post this, but just in case I don't. What is the name of the Railway Sub that operates through Winchester, Ontario? It appears to be a mainline. Also why does it have only one signal facing one direction per track, which results in trains only being allowed to go one direction? Link to comment Share on other sites More sharing options...

That's Canadian Pacific's Winchester Subdivision, method of control is ABS/OCS (Automatic Block Signaling/Occupancy Control System). West bounds on the north track, East bounds on the south track as per given OCS clearance. Link to comment Share on other sites More sharing options...

Shaun Posted October 7, 2009 Report Share Posted October 7, 2009 Pertaining to the metrolinx proposal to allow Tier 4 compliant locomotives to run on the Georgetown Corridor...how do they plan to do that when it currently doesn't exist? And since the MP40's the GO purchased are not compliant they wont be able to run in that corridor? Link to comment Share on other sites More sharing options...

And since the MP40's the GO purchased are not compliant they wont be able to run in that corridor? Tier IV comes into effect January 1, 2015 if my memory serves. But as the MP40's are only Tier II compliant (although rumour goes that EMD has made the 710 Tier III compliant), in theory you are correct - they would not be able to run on the upgraded Georgetown corridor.

Although I haven't seen any plans for GO to purchasing any more diesel locos after an order to be placed around 2011 - which would be for Tier III units.

smallspy Posted October 9, 2009 Report Share Posted October 9, 2009 The could always send about 10 of the MP40's back to MPI to see about making them Tier IV units They wouldn't send them back to MPI - they would either send them to EMD in London, or one of the contract warranty shops. And of course, that is assuming that EMD can make the 710 Tier IV compliant. Dan Link to comment Share on other sites More sharing options...
Shaun Posted October 9, 2009 Report Share Posted October 9, 2009 I saw that there are some sections of track standing beside the rail bed in the lower portion of the bala sub. Are they replacing tracks? Or are they removing one of the sidings? Link to comment Share on other sites More sharing options...

kellergraham Posted October 9, 2009 Report Share Posted October 9, 2009 Quick Question -- I should really know this Why is it that sometimes a non-stop signal is displayed on the same track but opposing direction of the train? For example, an easbound train just past a signal and it's equivalent westbound signal (on the same track) displays something like clear-to-stop. It only changes from stop to clear-to-stop after the last car of the train passes that signal. The engineer obviously doesn't see this signal. What's it for?

They upgraded their signal system about a year ago, which allows them to fleet the signals between interlockings in both directions at the same time - the signals will only display green (and red) when the interlockings are cleared through. It will also clear the blocks behind in the other direction immediately after the train has passed. Dan Link to comment Share on other sites More sharing options...

When an eastbound commuter train arrives at Vendome, the signal just west of the station is clear to stop, but the train is heading east.

What kind of signal is it, tall mast or dwarf? On CP, once the train is past the signal it changes to restricting so that the following train can enter the block and close up to the train ahead at restricted speed. All done to keep traffic moving. Question about Train Crews with CNHow offen are they away from home for 6 days stright, how Does that work out? Only on work trains, not often. In train service it's normally a 24-48 hr round trip. Double Sub trains are about 2-3 days round trip. Link to comment Share on other sites More sharing options...
