When gate is electronically closed, the train will not stop at it, instead it will try to ram it and if the gate withstands the impact, it will continuously drive against the gate until it runs out of fuel. Train signals will also not produce red light if gate ahead of the signal is closed.

Of course not, there is nothing in a gate that would tell a train to stop and even if there were, it could not stop in time. If you want a train to stop depending on the state of a gate you need to build a circuit setup.
