Chicago L Timetable 27/12/2014 at 00:33 #67074

WTT for the current weekday timetable, for the new Chicago L sim.
Purple line trains are identified with R.

Some brown line trains exit at Roosevelt, and are prefixed 9. That's what I could see them doing on Goroo, if anyone with local knowledge (pertaining to this or any other potential error) could advise, that would be great.

Version 1.0 of the timetable is currently available here, with an updated version awaiting approval.

7 times in the AM peak and once in the PM peak an Orange line train enters from Roosevelt, operates to Clark/Lake then exits at Merchandise Mart as a Brown line service, then about 90 minutes later the same train re-enters from Merchandise Mart, operates to Harold Washington Library, then according to Goroo (and all other CTA data I can find) the train disappears.

I believe this is a data error, and you are correct in that this train exits at Roosevelt, and operates an Orange line service back to Midway.

I understand this is done to provide extra Brown line capacity at times when the Adams/Wabash to Clark/Lake half of the loop is already at capacity.

Hmm. I can't find any entering Orange Line trains that don't have an associated exit at Roosevelt on Goroo, or in my WTT. sigh
Any idea which particular trains? It's very hard to pick out ones that are different from the rest in a massive sea of regular-interval services! Although I've done my best.

Edit: found 6 of them labelled as Brown-line trains. Argh. Thank you!

Yes, they all show up as Brown line trains in Goroo. I suspect an issue with the trip planner software prevents them from showing up in the Orange line section, which also means getting a Roosevelt time for these trains is not possible, and will need to be made up.

For reference the trains from the Orange line are (times at Adams and Wabash):
6:05am, 6:15am, 6:25am, 6:35am, 6:45am, 6:54am, 7:02am, 5:05pm. At a guess I assumed the Roosevelt time was 3 minutes earlier for all trains except the 7:02am, which I think should be 4 minutes earlier at Roosevelt due to conflicting traffic.

For reference the trains to the Orange line are (times at Harold Washington Library):
8:04am, 8:16am, 8:27am, 8:35am, 8:41am, 8:50am, 8:56am, 6:43pm. At a guess I assumed the Roosevelt time was 5 minutes later for all trains except the 8:35am, 8:50am and 6:43pm, which I think should be 4 minutes later at Roosevelt due to conflicting traffic.

Once your timetable has been approved I'm happy to play / audit it and give you feedback if you'd like. I've also been doing some research into the run numbering and consists, although can only find generic information and not specific details at this time.

Good God ... 30 minutes in, and already this TT has fried my poor brain. I've numbered the loop lines 1 to 4 (top to bottom), and put up a sticky note listing the lines each train takes. Once I get the hang of it, I'll get rid of the sticky note. :yikes

I have submitted an updated version with Leigh's suggestions. Thanks to Leigh for his information enabling this timetable to be corrected quickly. The source of BarryM's frustrations may have been some peak Orange line trains entering twice, which is now corrected.

The updated file is awaiting approval.

I don't find it that hard at all - maybe the advice for maxand would help you too: If you think it is hard with stickies, try it without them. Personally I don't care what's on the lines, it always shows in time at the junctions.

I should point out that my post was mainly for effect. I removed the sticky after about 15 minutes of playing. For the record, I don't think it's particularly hard. In fact, I was thinking it needed more trains ...

But thanks for your concern.

One thing I have noticed about this sim in general is how easy it is to lose loads of time in a very short space of er, time.

I started this TT from scratch - I'm 45 minutes in, and I've somehow lost 29 minutes despite all trains entering on time. I expect to be up near 1000 by the end of the day.

One of those trains in your WTT, B931, has a slight problem. It is timed at HW Library, then Adams/Wabash, then Roosevelt - unfortunately the sim doesn't allow such move. I ran it along this path, but had to let it run wrong-way to Roosevelt after giving the driver oral permission. The other trains (B932) don't include the Adams/Wabash timing point, so they're OK.

Yeah, I expect even more - if you divide it by the number of the trains, it doesn't look so bad. And if one of the trains has brake problems, the whole loop is stopped solid.

There are a number of trains timetabled to depart the same platform at the same time. So it's very likely the service that goes second will lose some time. Pay close attention to the timings at a few stations along the loop and that will give you an idea which one to send first for the least delay (assuming both are on time).

If I can offer 1 tip - I've noticed the Orange line trains enter then have a long sectional running time before being scheduled to depart from Harold Washington Library station, which means they often will wait there a long time blocking other trains behind them. If there is a train at Adams/Wabash or even Madison/Wabash, you may want to consider giving it priority to Harold Washington Library, as you can often hold the Orange line train a few minutes at the junction and it still depart Harold Washington Library on time.

Have you got the latest version of the TT? The one I'm running has all the correct locations for the B9xx trains.

This, along with some other errors like some Orange line trains entering twice, has been corrected in version 1.1 which is now approved for download.

I think this is to do with the times being rounded from half-minutes.

v1.1:

All of the Orange line trains between 6 and 7 exit to Merchandise Mart? Is this correct? How does one get to Midway to catch a flight during those hours?

That is part of it, but I also think Chicago don't produce a validated timetable, like many other railways. From what I've seen of Chicago I don't believe it is possible that 2 trains can stop at the same platform in a minute, even if one is in the first half and the other is in the second half. I might try to find some evidence of this in the next few days.

Even so, it appears there are a number of trains timetabled to be at platforms at the same time and half minute, which will definitely cause a delay if both trains are on time.

Because Chicago operate on a more frequency based approach I think there is a assumption that trains will be dealt with on a first come first served basis, regardless of timetabled order, or even if the train is early or late. I think I'll do some research into the running times of trains to determine how likely an on time arrival at the loop boundary is.

I think you may have misunderstood my post. I was trying to provide some context as to where the mysterious Brown line trains came from. Looking at both versions of the timetable I think you had the orange trains correct in version 1.0.

Having said that, there a few minor issues still with v1.1, in relation to times at some locations. So probably worth holding off on another update until I can provide a list. By then Danny may have also updated some of his great research on the run numbering, and that could also be incorporated.

Are you sure? I changed it so there are 7 orange line trains exiting at Merchandise Mart, using the times at Adams/Wabash that you stated. I think I'm missing some orange line trains to midway in v1.1.

I was going to completely rewrite it once Danny has released his data anyhow, there are too many inaccuracies and they're too hard to find!

There are 14 trains from the Orange line that should enter at Roosevelt between 0600-0659. 7 of them are genuine Orange line trains that go all the way around the loop and exit at Roosevelt. The other 7 of them are the hybrid trains that form Brown line services and exit at Merchandise Mart.

It's chugging away, looking at what's happening at 5:45am in Chicago as I type! (I forgot to leave it running Sunday Night after a very long day playing with real trains).

Regarding the Orange-Brown line trains, I've got those listed in my Timetable spreadsheet - they're the 5:40, 50, 6:00, 10, 20, 29 and 37 departures from Midway, and the 7:23, 33, 43, 52, 58, 8:07 and 13 departures from Kimball. Helpfully, it seems they get custom destinations in the train tracker, as the 5:40 off Midway is currently showing as being for "Downtown, Kimball", rather than the standard "Loop" destination (edit: and "Loop, Midway" on the return).
