But Hard for me to remember exactly as it only took. That route once, but by the 4th rail there was no more English on it , or if there was, it would be the wrong English to take it at that angle to the red, which wold be the reason why it went to the middle of the short rail
i will wait for others to comment
but since you were not sure where the cue ball hit on the fourth rail then we dont know what tract it took
