To piggyback on this great explanation, this is why the # of train cars/train sets is important, and why losing the 7000 series was huge. Not every line needs the same number of trains, because as the original asker stated, the distance between stations (and on each line) is variable.

For example, it takes about 102 mins for a green line train to complete a roundtrip, not including layover. For service every 8 mins, it would need about 12-13 trains to maintain that.

By comparison, it takes 186 mins to do a roundtrip (again, not counting layover) on the Silver line. For every 15 min service, though, which is nearly double the green line, you still need about 12-13 trains. If the silver line were to do 8 min headways (which I don’t think is possible w/o svc cuts on Blue & Orange), it would need about 23-24 trains

For a final comparison, If you use the red line, which takes about 148 mins to do a roundtrip, and has 10 min headways, you need about 14-15 trains. That number shoots to 18-19 trains to do 8 min headways

Take all this into account with trainsets being 6- or 8-car trains and you basically have how headways work and why losing so many train cars was detrimental

Yep, that was it

Another user error lol, I meant White Marsh, but White Oak in Montgomery county has been stuck in my head.

Carney is NE of Parkville, in this area, the train would be in or near 695, which is the dividing line. Since it would be coming from Belair Rd, I decided to do the Carney stop first and take a bit of liberty with naming Parkville since the MVA does the same thing (their Parkville location is actually in Carney).

This is something I’ll look towards changing in my revisions since it’s causing confusion

Ok, you aren’t telling me anything I’m not already intimately aware of lol. When I said do-able, I meant in the context of running more Camden line trains vs implementing this entire project, which is absolutely true. At the end of the day, none of this will be built, so you don’t have to worry

I’m aware. It’s there for the Guinness factory and to spur any eTOD, although that would require re-zoning and political effort (although what part of the project wouldn’t). Ideally, the stop would become more useful even if nothing was there if more Camden line trains were run (or at least run at the frequency of Penn line trains) which is strangely the most do-able part of this whole map.

Nothing shown is really outlandish other than the segment from UMBC to BWI on the E and the detour through Curtis Bay on the D, which actually isn’t shown. And outlandish is sort of hyperbole, none of these lines are as along as BART for instance, or the Red or Silver lines in DC

User error unfortunately. I think that was supposed to be the original Highlandtown stop before I switched things around

Hi all. I wanted to create a rail system in Baltimore ther does what it's three existing rail systems currently don't do or don't do well at: provide adequate service for the people. This map is a combination of the current Metro SubwayLink, the original Baltimore subway master plan and the CityLink network established in 2017.

I want to note that this is a fantasy idea, is unfunded, is not currently in any sort of planning stage nor will it be anytime soon. I just want people to enjoy what could be!

I used to do Reservoir Hill to DC. I’d take the bus down north Ave until they redid the bus system, then I had the option of that, or the slightly longer bus more confident bus from directly where I was staying to like a block away from Penn. I’d recommend that neighborhood, you’re near a park, the zoo, good areas to walk and a lovely neighborhood cafe called Dovecote. And if you have a car, you’re not from from either Penn or West Baltimore stops. Don’t take the Camden line, focus only on the Penn, it has more trains, is faster, and runs weekends as well. Especially consider Station north as well. Good luck

I remember when Yang’s was just a regular corner store that we would terrorize after HS on our way to the G8
