Can anyone confirm if these types of wagons are in current use, please, and what for? Are they used for ballast and if so, how are they unloaded on site (I'm assuming with some sort of tracked excavator or bucket machine)?
I have seen a number of MTA or MFA type alongside the ECML, particularly the black EWS-branded (presumably ex-Loadhaul) variety but not actually in moving trains.
Also, were the EWS liveried MEA wagons (as per Bachmann model) used for ballast or some other purpose?
Are there any small "virtual quarries" in yards or locations which might be suitable as the basis for a compact layout?
