I get more and more frustrated with this country every day! I am reading this thread with my mouth wide open- In my naivety I thought for a split moment that we might be EXPORTING biomass, or at least moving it to industry at the south end of the country. Never mind that we have a super climate and lots of unused land across the west and north of the country, sure why would we be bothering with that biomass stuff? (And don't get me started about natural gas!)
Back on topic, it would make sense for IE to use containers in the short term for biomass. A 45' high cube container for example holds 86 cubic metres, about 2/3rds of those purpose built Drax wagons. I'm also thinking that because the product is pellets, the might use something like a 30' IBC/IFF style of container. These have hatches in the roof for loading, and are emptied using a tipping road trailer. Not sure what kind of weight is involved with biomass- I've seen 45' versions of these containers for carrying light pellet product like plastic pellets. It would certainly add some variation for modellers.
Is there enough freight to Ballina yet to warrant the re-opening of the western rail corridor?!? With Sugar Beet coming as well it could potentially be a very busy line once more.... (as he drifts off into an orange black and white filled dream world...)
