What is the maximum number of train that can run in the game?

In theory it's unlimited, it entirely depends on how much processor and memory your device. The number can be configured in the game settings, the default is 500.

There is a global pool with a hard limit of slightly over 1 million vehicles total in game, across all companies. In this context every car on a train counts as a vehicle. (Also airplanes count as 2 vehicles, helicopters as 3 vehicles, and I think articulated road vehicles use up a vehicle per articulated part.)

Isn't there a limit at 5000 for trains you can build ?
This could be increased if you buy other companies.

There is a setting called 'maximum number of trains per company. I spammed 99999999999 into this box, the maximum, at least on the JGR patchpack I use, is 10,000 on this setting. or rather, that is what it set it to when i spammed lots of 9s. I'm guessing with some effort you could modify it in the source code should 10,000 not be enough. In my experience, even my i7-8700 is rather unhappy when you get to about 4,500 trains, at least on the map size i am using
