Unlike the rest of the locomotive, I wasn’t very happy with the look of the original cast plastic coal load which is simillar to other Bachmann steam locos. The plastic coal load is tight press fit in the K-27 tender, easily removed to access the three switch’s and circuit board. I removed the original coal load and made a “tray” from styrene, 2mm for the base and .5mm for the sides.
I crushed up a couple of lumps of real coal, souvenired from the load 71/2" steam club. To reduce the amount of coal required, a plastic foam core was hot glued to the floor of the tray. The crushed coal was piled into the tray and fixed in place with diluted white woodworking glue. The glue took about three days to dry, but now is one solid lump.
The new coal load is not fixed down, still leaving the tender electrics accessiable. Wayne
