It depends ona number of things, and it's not an easy question to answer since you haven't given us much to go on. (I.e., I don't think we can help you answer your question without more information.)
Are the two trains on the same track? Are they headed towards each other or away from each other? How many cars (and what type) is each train pulling? What color is the bandana worn by the engineer of train b? Are these American trains or Italian? And of course, remember that if the bridge is out, and the trains don't stop, they WILL crash into the gorge and burst into flames.

It will also help to know which direction each train is running in...If they're both going the same direction, there is zero chance of them crashing, unless train b is going faster than train a.
Here's the basic equation...
Rate x Time = Distance
The rate is the speed at which each train is going.
If you know the speed of each train, and the distance each one has to go, you can just plug these into the equation to figure out how much time it will take for each one to get to where the other is.
As an example:
Train a travels at a speed of 100 mph.
The distance between the first station and the second station is 200 miles.
Therefore, Rate = 100 and Distance = 200, so the equation reads:
100 x T = 200 and can be converted to read:
T = 200/100 which lets you figure out that:
T = 2
If you do the same thing for Train b, you can figure out how far each would have to travel in order to run into each other.

well with the info given your probability would be very low considering we know no known speed so that wont help, also it would be nice to know a direction, if they are going in opposite directions they wont hit, and even if they are going the same direction we would need to know the speed, and if they were heading towards each other whos says they would collide.
YOUR QUESTION IS FLAWED, TRYING FIXING THAT FIRST

How fast is each train going, and which direction is it going in? You need more information before you can solve this problem.

It depends on the speed of train a and b.
