Maybe a minor bug, but I came across this when I was messing with locomotives.

As the title says, a locomotive's open_sound and close_sound never play. For other entities these are used when their gui is opened/closed but this doesn't happen for trains. And since the fields are defined for the vanilla locomotive it is not like this is supposed to be an unsupported property of EntityPrototype base class, or is it?

Thanks for the report.
Somewhat recently I was discussing this with our sound designer and we decided that those sounds should not play for the locomotive since by clicking a locomotive a remote view is opened. In 2.1 the opening of remote view plays a sound instead.
So the only thing to do here is to remove open_sound and close_sound from the locomotive definition.
