Is it at all obvious when you pass it?
No, not really. Don't think anybody passing would be aware of what it is
Just a 2 metre high wall, with a steel louver cover over the top with access hatch. No specific ID.

Sorry to bring this thread up again, but as I was up that way yesterday, I went and had a look. Would it be this?
Where it is critical to reduce noise and vibration, such as in Urban areas, the concrete slab can be supported upon soft resilient bearings. This configuration is called "floating slab track" but is expensive and requires more depth or height. The benefit is that it can reduce noise and vibration by a significant amount.
Alternatively, the rail can be supported along its length by an elastic material; when combined with a smaller rail section, this can provide a significant noise reduction over traditional ballasted track, however this is not suitable for high speed or heavy haul lines where the trend is now to move to even larger rail size.
