I'd be wary about leaving a 2k bike at the train station. It's too tempting a target unless it's locked down so tightly it's more effort than its worth to steal, but 2k is worth a lot of effort.
Camouflage may help work, wrap it in tape to give it a scuffed knackered appearance and choose a less desirable shape. MTB style tend to get a lot of attention.
All locks can be broken and even when the theif can't do it themselves, they sometimes just smash your bike up in frustration, that happened to me once, lock had obviously been attacked but when they couldn't get through they smashed up both wheels and I had to replace them and the rear cassette.
I'd double d lock it at the very least with good quality locks. I regularly park in at a train station, every so often I'd return to find a number of broken locks on the floor, usually the cable style locks where somebody has obviously come in and taken a few.
I have a fairly nice hybrid much shinier an newer than most of the others on the racks so to compensate I lock it up securely with a good D Lock and a seperate thick cable lock to secure the wheels and frame. I also leave it in the secure bike parking area, not perfect, but it's swipe card access only and does add another layer of difficulty to an opportunist.
it's more about pointing them in the direction of a bike that's easier to steal than yours, but if it's a really nice bike, it's that much harder to redirect them!
I can vouch for Squire D locks, I've got one I absolutely love, it's been attacked on three seperate occaisons with only cosmetic damage to the lock leaving it battle scarred and proud.
