![]() ![]() USRC is where modernization is needed and that’s underway. in terms of operability, reliability, and cost, GO has a good modern plant. That’s a remarkable positive of the GO system and certainly is the envy of plenty of transit properties. Other than the USRC, there isn’t much really old stuff left out there. What I will offer is that pretty well all of the CTC infrastructure on all GO lines is either new build within the last decade or renewal within the last decade or so. those who are hands-on will have their praises and gripes for each. It is likely a Honda vs Toyota kind of thing. I’m not a signals engineer nor a maintainer (and there may be one or two lurking), so I won’t comment on the relative technical merits of one versus the other. I'm fairly new to this forum, and I'm loving the information that's available here! So far I have found this is done through an ATCS radio but I'm not entirely sure. I've been trying to research if most crossings, signals, and interlockings use a data radio to transmit information to each adjacent location. I'm not sure if this is applicable to the Metrolinx network. For example I have seen that there may be conflicts with at grade crossing that use a DC coded track circuit since electrification requires a return DC through the rail. ![]() I wonder what are the compatibility issues with existing CTC equipment. It would be interesting to see how Metrolinx further transforms their network as they proceed to enhanced train control and electrification. I guess as an example, that's why the EU blocked Alstom and Siemens from merging last year due to fears of price gauging. And yeah that's what I figured in terms of coming down to the bid. Lately? Wice hasn't worked properly/consistently since it went live in early 2015.Ĭlick to expand.Hmm. At the end of the day, ultimately, all of the components are now plug-and-play (more or less), and ultimately they will play nicely with the others (again, more or less).Īt this time, Metrolinx is using a couple of spare desks on CN's Siemens-derived CTC-II system to do their dispatching, before their own system goes live next year (it is hoped). And all of the companies (and feel free to add Siemens to the mix as well) can be pretty aggressive in their pricing when the time comes for them to want to win a particular contract. I think that it comes down to who wins the bidding/tender in the contract at the time. Alstom and GETX have also been used in other installations of late, in specific locations.Īs for which is better than the that doesn't seem to really come into play. I'm still waiting to get confirmation back from a friend of mine. I *think* that they used Safetran components on the Weston Sub, but AnsaldoSTS in many places elsewhere on the Metrolinx network. ![]()
