The Accurascale HEA fills a long-standing gap in the story of this classic 2,000-strong wagon fleet, bringing the as-built HBA variant to the 4mm scale market for the first time alongside several previously unmodelled variations. A familiar sight on domestic coal flows from the late 1970s through the 1980s and 1990s, these workhorses survived in service right up to the 2010s. Overlooked for far too long by ready-to-run manufacturers, these iconic hoppers are well overdue the Accurascale treatment and have been faithfully reproduced in meticulous detail.
