Some NS trains have or had a doors-about-to-close sound very similar to the distinctive guard's whistle sound (of which I own one). Can't remember which type though, possibly the Koplopers.
The VIRM had that from new in 1994. They were the first Dutch trains with any form of hustle alarm. I think the Koplopers had it retro fitted when they were rebuilt about 10-15 years ago.

As @Bikeman78 mentioned, VIRM and Koplopers have them, but newer VIRM classes and/or refurbished sets have a beeping sound (not sure where the cutoff is as I am not really into subclasses of rolling stock, just a regular user). Also the now retired Buffels (DM'90) had a very loud whistle sound when the doors closed.

It seemed like it actually was a whistle connected to the same compressed air circuit that closed the door. So as pressure built, the whistle would first sound, then as it built more the door would start to close.

No idea about the mechanics behind the system, but that's exactly what happens indeed. The sound stops as the doors close.
