Dear Deirdre

We always see Trains - Up and Down moving either in North - South
OR East - West Direction.

Example : Four Tracks

1. Train 1 moving Towards North On Track 1
2. Train 2 moving Towards South On Track 2
3. Train 3 moving Towards North On Track 3
4. Train 4 moving Towards South on Track 4

Question
--------

As attached in the figure viz Trains Direction Movement 1, Will this type of Trains Direction Movements also applicable i.e. Railways running in real scenarios in specific countries?

i.e. Some Trains Moving in North-South, South-North Direction but at the Same time, Some Trains are also moving in East - West, West-East Direction.


Cases
------

1. Train 1 Moving from North to South , Train 2 Moving from East to West.

2. Train 1 Moving from South to North , Train 2 Moving from East to West.

3. Train 1 Moving from North to South, Train 2 Moving from West to East.

4. Train 1 Moving from South to North, Train 2 Moving from West to East.

5. Train 1 Moving from East to West, Train 2 Moving from North to South.

6. Train 1 Moving from East to West, Train 2 Moving from South to North.

7. Train 1 Moving from West to East, Train 2 moving from North to South.

8. Train 1 Moving from West to East, Train 2 moving from South to North.

Either Train 1 or Train 2 has to halt in all cases so that the other Train moves in the specific direction to avoid collision.

Awaiting your reply,

Thanks & Regards,

Answer
None of these scenarios need to happen.(at least not often)
In modern rail systems, the people controlling the trains are usually able to time the trains such that there is little conflict. In many places there is only a single track - not two, so North-bound and South-bound trains will occupy a single track. There may be a siding in various places and one train will be switched to the siding to allow trains to pass each other, but the bulk of travel takes place on a single track. Crossings are less of a problem - it can be a simple matter of controlling the speed of trains to insure they aren't at tne crossing at the same time.
