About Express
Three separate odds existed for Express during the Winter 2025 Christmas event: 1 in 30,000,000 in the Snowy biome, where it competed 50/50 with Arcane : Dark, 1 in 90,000,000 as a breakthrough, and a chance through the Roulette game mode as an Exalted prize (0.05% in Regular, 0.5% in Rare, 5% in Mega). The Sol's RNG Wiki now lists it as unobtainable. Ten creators are credited, from leoalmlo and cclyran to 47_oticat.
It is a train in the spirit of The Polar Express, with a color scheme like Santa Frost. The black locomotive has four big wheels and a small one on each side, blue-lit windows, a snow-dusted roof and glowing snowflake ornaments at the front, plus a bright yellow headlight. A red carriage behind it carries presents and a flat snowman, like a child's wagon, and the player hangs from the back of the locomotive. The train runs on a light blue rail that keeps moving forward with spiral effects.
No in-game description is recorded for it.
