Spare Rail Stack

Spare running rails laid out beside the line for the relaying gang, the partner of the Sleeper Stack: lengths of the kit's own rail section, 8 m long (two track modules), rested on three short timber bearers cut from old sleepers.

风格：low-poly, flat-shaded vertex colors, no textures, single shared material, so any set of these merges to one draw call; shares palette and scale with its kit
