@EpiEMS Albany had a pretty big "MCI" a few weeks ago, a car(ford f350 super duty, quad wheels all that crap) into a building (injuring 20 something people, i want to say 24). It's quite hard to get an MCI in a major city, just due to the large amount of resources we have... However all of what desert said was basically there. Both CCT rigs were called, 6 additional ALS rigs, 10 transport vanbulances(From mohawk*private*). The sheriffs office had the undersheriff there(in charge of the EMS unit), public officer, 8 squad cars from albany PD (set up a fantastic perimeter and staging area i may add). They also had a on-site communications "expert" *i dont know qualifications so i won't call them an expert*, and the CCRN's from one of the CCT rigs were the triage folks.
My biggest worry is a commuter train accident - 500 passengers on a single train plus limited access to the tracks means I'll likely need more rescue staff than I can get for extrications.
For this, NYS has something in place already, called New York Task for 2 (they handle the rest of the state, literally anything other then NYC.) the one exception was 9/11. NYTF1 is city. They have a ton of people available (i think they can deploy up too 100 people in under an hour +travel time ect), in reserves and active. Since you like sources:

Its kind of cool how they work because the military will let them onto bases in NY and military pilots will fly them if a "heavy" deployment is deemed necessary.. In conjunction with NYSP. Albany county itself has a USAR team, so those 2 together gives you about 120-140 people?

As well as Albany Med has helicopters stationed at it, so if need be for flight (i cant see why, but who knows.) that can happen. Albany med also has a neato program in my opinion, it asks doctors voluntarily to be put on a list in case of a MCI on a massive scale (bomb, building collapse, anything that could be +100 severe injuries), and if they get the call they come in **clock in to get paid for it**, and work, Just so you have more doctors available, and since it's voluntary, it would be safe to assume if they get called they will come, unless they are not in the area, ect. I just think that bit is really cool. **Source: trauma surgeon at Albany med current volunteered on that list**
