Thread: CNW Chicago Division Progress - 2021

  1. #21

    OK, I'm going against my better judgement, but plan on a work-in-progress release sometime this week.

    It will be available in the store at DigitalRails.com and I'll be asking for a minimum $10 donation. Go read the website to see how those proceeds get distributed... hint: it ain't going in my pocket...

    To set expectations...

    • The $10 gets you to the route as it is today, with no promises there will be support or another release anytime soon. I've seen what people have said about the Sherman Hill beta, and honestly don't really care if you think you got ripped off. $10 for over 200 miles of running and 5000 custom objects is a bargain....
    • No refunds on donations. Try to do a chargeback, and I'll fight it.
    • It's around 10Gb download and almost 12Gb unzipped due to the photo terrtex.
    • It's fully signaled Chicago to Rochelle
    • There's not a lot of scenery across the entire route
    • There are probably a few track database bugs thanks to some unfixable issues in TSRE, but I've tried to fix all of those in advance.


    More details once I finish up the final testing....

    You can show them to me and maybe I can help you fix them.

    It's the vector flipping. I'm finding it on vectors I haven't touched in weeks.

    Upload from Digital Rails is currently being set up... Hopefully it will be available later tonight.

    For now, you can go directly to the Store @ https://gum.co/cnwchicago

    Thanks to all who have downloaded and provided some feedback. A few items in the route have been updated and a patch uploaded to Gumroad -- click on the download link from your receipt and you should see the new file.

    For those who purchase on or after 15-Feb-2021, there's no need to download the patch.

    Thanks again to all those who've taken time to donate and download the pre-release.

    There will be more coming shortly... as a word of warning, don't do a whole lot of activity or path work on the Harvard Sub... Big changes are coming there.

    For those new to my building approach... I try to mirror Agile, and work in sprints. Agile in development groups for my real job usually follow two week blocks, but my sprints run about a week, with individual sprints having anywhere from 4 to 30 miles of track each. The reasoning behind this: when you can achieve something quickly and regularly, you don't burn out as quickly...

    The release for the Geneva Sub end to end took about ten weeks, with six track sprints (MP15 to MP12 -- MP05 to MP12 -- MP15 to MP24 -- MP24 to MP32 -- MP32 to MP59 -- MP59 to MP68) plus a side sprint for doing the CTA trackage, another side sprint to do a mass update on my naming convention for shapes, and then another two weeks of debugging and doing repairs before the release went out.

    With that release done, it's time to move onto the next sprint. And its a doozy....

    The original route from 2010 was built with X-Tracks, and that was later replaced with Scalerail. While I've done all new track builds with yard spacing (4m track centers), the original mainline from downtown to Harvard (about 63 miles) was still done with "standard" 5m track center spacing. I've left that alone up until now, but it's time to convert that entire 63 mile stretch of track over to 4m track centers...

    The other driving issue is alignments that are considerably off from the Google Imagery:











    There's only one way to approach this.... rip it all up and start over, like I did on the Geneva and Clinton Subs.

    And what a better place to start on the Harvard than in Harvard...



    I started that sprint back on Thursday, and after a couple days of deleting and replacing, I'm pretty happy with the initial results:





    As of tonight, I've got Chemung to Harvard re-done (approx 4 miles), as well as MP63 Harvard to MP52 Woodstock, which is about 15 miles of track in total. Nothing was saved with the exception of the highway overpasses...

    Tomorrow I can start on MP52 Woodstock to MP43 Crystal Lake -- the alignment is off enough from imagery that it will also be a rip out and realign. I'm also using this time to fix some of the grades to match a set of track charts I didn't have for the original build... which is amazingly easy now that TSRE allows me to key in permile as used in the track charts.

    That ends the first sprint.

    The next sprint will be MP43 Crystal Lake to MP29 Palatine. The alignment is fairly good, so that stretch will just be a matter of replacing the 2tStr_W tracks with 2TStr_Y tracks, which will also require re-doing crossovers and industry tracks, but that's fairly quick work as long as I don't have to recalculate curves.

    That's followed by MP29 to MP17, where the alignments stray off again, and MP17 Deval has some serious trackwork to contend with plus a yard... There's also a yard at MP33 Barrington to deal with.

    Then the real fun starts.... MP16 Des Plaines to MP0 Downtown. The track alignments are is mostly OK with imagery up to MP3 Clybourn, but there all bets are off, and that's going to involve a lot of curves to re-work.

    Somewhere in there I'll need to address the New Line, which also has some alignment drift, and re-do the portion of the Soo which appears at Deval.

    I'm hoping not to have to mess with Olgilvie at all, so there will be some smoke and mirrors at the first curve around MP0.6 Northwest Junction (where the West Line and Northwest Lines split) to transition back to 5m track centers.

    My guess is this will keep me busy enough to get to the end of March before I package it up for another release.

    After that, it's north from Harvard to Janesville and Madison, plus Crystal Lake to Richmond. Mostly alignment drift -- those sections were built out after I'd downloaded the original Google imagery using SRT so it should go quickly... Fortunately, Janesville to Madison was already converted to yard spacing.

    Interesting fun for Sprint 2... I've got a 13+ mile straight run between Dundee Rd in Palatine and Three Oaks Rd in Cary...

    When I set the QDirection between the two endpoints, my alignment ends and begins perfectly, but curvature of the Earth (or just the quirks of the G-H map projection...) sets in, and has the middle off by almost 3M....

    Thanks to Dave N who suggested breaking the line up into multiple pieces.

    Basically, I found grade crossings at 3-4 miles apart, and ran four separate QD's between those waypoints. Now it lines up perfectly.

    Glad I found this out now so I can plan more 3 mile blocks... Palatine to Des Plaines is another 13 mile straight section I'm tackling tonight, followed by Des Plaines to Clybourn, which is also 13 miles give or take.....

    Screenshots later....
