It was running for many years on our Tumut Branch Line model without any problems it is only recently the derailing is a occurring.

There is not space to put Kadees as the bogies are close to the end of the carriages and the existing fitting does not allow one to be fitted.

We are using the Peco short points.

The carriages were touching when pushing that is why I removed the concertina section and now they do not but still derail

Check for clearance between the bogie frame and steps. On a sharp curve it will be very close. If the steps have recently been bent (or straightened) then that could be your problem. With adjustment the 620/720 will easily negotiate sharper than 18 inch radius curves.
