 == The 4 and the IRT Jerome Avenue Line == 

 What is special in the track configuration near 161st and 167th Streets of IRT Jerome Avenue Line? The number of tracks is still 3, and only 2 of them are in use. Where am I wrong?    
 :The express track begins south of 138th Street via a diverge from both tracks. There are diamond crossovers north of 149th Street from both local tracks to the center express track. North of 167th Street there are two single crossovers, to the middle track northbound and from the middle track southbound. See the track maps, Uptown and North from this page. Given the fact that the schedule shows the express track in use by revenue trains from 125th Street to 149th Street and from 167th Street to Burnside Ave, it is not appropriate to say that the two stations in between don't have revenue service on their middle tracks. It's original research to say either way.   •   
 ::There's something that I don't catch. I have both those maps and those schedules saved on my local disk and permanently check myself using them, and still don't understand what kind of information we can get from them now. There are many crossovers in the system, and none of them lead to such a conclusion. The schedule, as far as I see, doesn't show tracks. Tell me please, is there a train that skips these two stations?    
 ::P.S. The schedule explicitly shows in white the stations that are sometimes skipped/bypassed, and in black the stations that are always served. There is 1 white station, 3 black ones and 3 white ones. The 2 discussed stations belong to the series of 3 black ones. 
 ::Moreover, I suspect that even after the 3 black stations the train stays on the local track and skips the white stations like a skip-stop train. There is no crossover that would allow switching back to the local track before Burnside. Also, the schedule says 'non-stop' and not 'express'.    
 ::P.P.S. No, I'm sorry. It's a full express (after 167th Street), and it stops in the middle of the Burnside Avenue station. But the tracks configuration allows this.    
 :::Those trains that run express, terminate at Burnside Avenue and then go to the yard. 
 :::Your comment about reading the schedule and trying to figure out which tracks are used goes back to my problem at the beginning. We are both using original research and synthesis to say which tracks are used. That is why I was uncomfortable even including it at all. That is why I removed it from those two stations (161 and 167) by saying, ""based on the track configuration in the area"" and service patterns, ""this is not appropriate here."" In other words, it is unsourced information.   •   
 ::::But at least according to the source, ""Train always operates and always stops here."" We are writing sourced articles, aren't we?    
 ::::P.S. 
 ::::* Thank you for checking my work, today too. I hope that was the last time. 
 ::::* I keep waiting for the final decision on 161st and 167th Streets of IRT Jerome Avenue Line. I need it to continue with my layout diagrams. 
 ::::* Can you tell me what's wrong with Roosevelt Avenue / 74th Street that appears in the text as Jackson Heights – Roosevelt Avenue / 74th Street – Broadway?    
 :::::As to the tracks at 161st and 167th; yes the 4 train always stops there, but there may be a delay to service as an in-service 4 train bypasses them on the middle track. That's why I removed ""2 in revenue service"". I would prefer the infoboxes for both stations remain as ""3 tracks"" with no extra information. We can't discover fro
