This topic will be about the "what ifs" of the New York City subway.
For much of it's over 110 year history, the New York City subway is rich in events, projects, proposals and everything in between that either happened, almost never happened, or never happen at all.
By changing one event in the system's past could have major effects in both the short and long run.
Like for instance what if the IND second system, or parts of it was built and opened, or what if the second avenue subway was completed before 1950.
I've been wanting to create a topic like this for awhile now, here it is, I present Alternate subway history!
The format will be, a scenario will be posted, for example "What if the IND second system was built and opened".
The original poster could start talking about the senorio in the starting post or let another person start talking about it.
Senorios covered (So incase this topic blows up, and we wont have duplicate starting posts.
I'll start,
What if the subway was never consolidated and the IRT BMT and IND remained independent companies.
Let's discuss it 
.
I might have in the past made a topic something about this.
