NewGRF Technical Discussions • Native support for pull-push trains now implemented

Thanks to 2talltyler, vanilla OpenTTD (nightlies) now supports native push-pull trains operation.

https://github.com/OpenTTD/OpenTTD/pull/15379

This works out of the box when a train has an engine placed at the rear, including multi-head parts.

There is also a NewGRF flag to allow it for non-engine parts, https://github.com/OpenTTD/nml/pull/420 And a variable to test: https://github.com/OpenTTD/nml/pull/421

So authors now no longer need to implement complicated sprite-replacement tricks to make push-pull happen.
