[Opinion and Bug] Point sound axis direction and unplayed point sound

[JunmoreHeavyBox]

Description

• Bug
  Except for the switch, without playing point sound when rail crossing.

• Opinion
  When using a single switch sound, regardless of the direction of the train, the switch sound is played by the front axle. Instead of the rear axle playing a switch sound when the train is moving backwards.

Point sound:
At present, these are omitted for crossing rails on a route where switches are in use, but all other routes should be unaffected.
I haven't quite figured out the 'best' way around this. It probably wants a specific new command to trigger point sounds.
(The other rail crossing rail 0 trigger is a classic example of a horrid legacy bodge)

Axle trigger:
A little wary of changing this.
As a general rule, the cabview position is somewhere close to the front axle, hence why I'm sure the original decision was made.
Any change would probably have to apply to all stuff (unless controlled by an XML parameter), and would then lead to it's own set of bug reports.....
