Accurascale have announced plans to produce GBRf IIA biomass hopper wagons in OO!
The IIA biomass hoppers follow the previously announced HYA/IIA coal hoppers, and feature several notable changes; including the distinctive roof doors and operating equipment, as well as the WH Davis revised design of end plates, plus door master controls and four additional small boxes per side that contain the magnetic switches on the real thing for door/hopper operation.
Decorated samples of these wagons are due later this year and should they meet with Accurascale approval they will move on to production, with delivery scheduled for Q2 2021.
