Yep, the Biomass (wood) pellets for Drax come into Liverpool and are then loaded onto specially designated goods train which take the 'cheap route' through Rochdale and Calderdale to get to Drax, rather than the express line through Manchester and Huddersfield where they might risk delaying an airport express!
Before Lockdown 1.0, when I was commuting on the Calderdale line to Leeds, at 0630, my train would often be delayed by one of these Drax trains coming through. Far easier to stop a two coach commuter train than long goods train. You could smell the wood though, it was unmistakable and strangely evocative.
Quite eerie, standing on the platform at Sowerby Bridge as this train approached from the dark, pulling a minimum of 20 wagons of biomass. By the time the diesel engine had gone through and half a dozen wagons had passed, you could no longer hear the engine so wagon after wagon would go past very quietly and disappear again off into the gloom.
