But which of these connecting directions is most important?I think the problem here is that you have two hourly services - one running roughly N-S and one running roughly E-W, where passengers may reasonably want to connect in any of the four combinations (N-E, N-W, S-E, S-W). It's plainly impossible to construct a timetable in which all of those connections in both directions are reasonably timed (unless all four trains heading in the four different directions turn up at the same time every hour and then spend 5 minutes waiting for each other). If we want all interchanges to have decent connections, then the only likely way to achieve that is to make all the services more frequent (which sadly we don't have the infrastructure to do)
N-E is between Birmingham/beyond and Cotswold line stations, but not as far as Oxford which has quicker direct trains from Birmingham
N-W is between Birmingham/beyond and Worcester/beyond, for which there are other direct trains available
S-E is between Cheltenham-Cardiff and Cotswold line stations, but including Oxford in this case.
S-W is between Cheltenham-Cardiff and Worcester/beyond, for which there are other services available by changing at Gloucester.
So I suggest the most likely connections are S-E then N-E, and ideally the timetable should have the northbound and southbound trains stopping simultaneously with an eastbound about 10min later and a westbound about 10min earlier. There are doubtless may reasons why this won't happen.
