is there a limit for the amount of trains per session?

Subways and railroads
let's say I've built every subway line for NYC and had it in a route similar to jeffmorris's "NYCTA 2012" route with every station and yard included, is it possible that I can run all the trains(IND/BMT and IRT) in one session?
 
Why would it lag? I thought it would be good to see all lines running in one session, but I just want to know the pro's and cons
 
I found by trial and error on my own route that the answer to your question depends on a number of things all interconnected. In my case I had a couple of detailed urban areas which I could usually drive through OK unless there were several AI trains all trying to do something at the same time. Then the program would crash. I solved it by removing a couple of the AI trains. On the other hand, I could set up a session in a rural area with a larger number of AI trains and everything would be OK.
In one of the detailed urban areas, I thinned out the details by using backdrops in the mid distance instead of 3D buildings. That helped too.

I found that if you have many AI trains running at the same time, some of them are prone to make a "mistake" while others run fine. Then, when you save the session, let's say that one consist is at one end of the route waiting for a green signal, (or in a wait for command) and you of course don't know because you are operating at the other end, and save... when you return opening where you left, that train waiting may not continue when the signal goes green (or the command is frozen), sitting there forever. Or in another stance, a train involved in complex AI switching, caught in the save, may run crazy when returning to the saved point. If you know all this, being careful, you may get by with little problems.
 
The ghost in the machine at the crux of this is System Resources..... If you run a TRS'06 Route, with TRS'06 locomotives, in TS12, on a 4th Gen i7 with a Titan Series Video Card, I could easily believe you could run up to 100+ trains no problem....

But lets say you have some Trains with JR Late Model TS12SP1 only locomotives, and some TS12 Speed Trees with some TS12 Nightmode Buildings by Dave Snow..... Now when you meet say, more then about 3 AI trains in the same spot, your game drops down to 4 FPS..... Or lets just say you do the first scenario with a 2nd Gen Dual Core and a GTX 750 and encounter the same problem or worse.....

Keep in mind that TS12 at least, is an outdated 32bit Game Engine that can only use a maximum of 4GB System Ram, and this plays a huge role here because your TADDAEMON needs that ram to pull assets from your library and give them to the game to display. Ultimately, I have tended to feel like (This is a hunch), that the one thing that holds TS12 back the most is the RAM Limit and how that plays out with TADDAEMON. Pretty much everything after that is how good your Graphics Card is.

I found a similar issue. As the asset load would put a load on the simulator, the AI would get confused and start missing their track marks. This in turn as we know wreaks endless havoc amongst the drivers. They seem to then go off on tea and coffee breaks, perhaps partaking in something a bit stronger, then come back to work in a rather unfit state.

To compound this issue, add in a lot of interactive industries, and other scripted items, and they eventually go on strike and go home. I have actually found that I've had to replace a bunch of MIN industries I setup all over the place with simple fixed tracks and "pretend" that they are interactive. It relieved a lot off the simulator and everything seemed to settle down.
