I’ve been working on a couple of addons for the LGB long (`54’ in 1:29) flat.
The first is Thrall style straight tapered bulkheads and log bunks. Shown here painted for my logging branch operated by the Lorax Forest Management Group.
Second is a crib and wheelsets for a wheel car load which includes replacements for the deck pieces to simulate steel sheet.
