Excellent news but the concept is not new, nor unique. A few years ago Redland had their aggregates trains with built in conveyors and discharge conveyor to unload "over the fence" if needed. Are any still running? More recently, sand for Ravenhead glass at St Helens has been unloaded by grab reaching over the lineside wall into the train. Perhaps time to revive the Blatchford container unloading crane? This looked like an overgrown twin mast tracklayer that could travel with a container train, or start a new service from any site with two parallel sidings and road access.
