Do you know what sort of scanner they use...? 2000x3000 is typical of the sort of res you'd get from a flatbed scanner using a 135 adapter; "proper" film scanners tend to give much higher quality pictures - as Roy says, 3200-3500dpi is about the base and higher DPI appears on some (but I think much higher than that is beyond the revolving power of most film stock anyway, although grain detail is still a thing at higher DPIs).
Regardless of the bit depth of the finished image, the dynamic range of the scanner itself can be a big factor before you get to that stage - there's plenty of scanners (esp. of the flatbed kind) out there that might have a smaller dMax than the exposure you're putting through them, so of course you'll lose some detail regardless of whether you use an 8bit, 10bit or higher format. One (flatbed+adapter) scanner I used for some of my 35mm slides was unable to cope with a lot of my pictures (I seem to remember loads of my XP2 negs having a pretty colossal dynamic range - at least five or six stops) due to dynamic range limitations; I eventually spent a fair amount of money getting them scanned with a proper film scanner for archival purposes. If I still shot in film I'd weigh up whether it was worth buying a basic one myself - last time I looked there were several available for under £300.
Beautiful pic of the ramp at the railway station BTW. Oblique lighting like that is a godsend for B+W

You could pretend you'd been there on your holidays from those pics
