After several minutes the train slowed and the carriage was filled with an orange glow as they rode into an enormous cave lit by countless flaming torches dotted throughout the cylindrical space as far as they could see above and below them. They came to a stop and were suspended in the centre of the space on a massive, rusted circle of metal that looked like a cog from a timepiece. They could see two more Wonderground lines dissecting through the cog forming a floating metallic snowflake that floated in mid-air within the cavern. A high-pitched, screaming siren barked rhythmically and echoed through the cave, disturbing a colony of hundreds of tiny white bats that skittered around the carriages before divebombing below them and out of sight. The alarm stopped abruptly and was replaced by a second sound. A series of short blasts on a whistle. The carriage began to shake beneath their feet. The plates by the cake cabinet vibrated loudly and the cabinet light flickered intermittently. They held each other as the screeching, scraping sound of machinery filled the carriage and the view out of the window slowly changed. They were turning! The metal cog contraption was a turntable and they were being redirected along a different line of tracks. But to where? The carriage shuddered to a halt as the squealing metallic noise ceased. They had turned approximately 120 degrees. The nose of the Shadow Kiss crept forwards as the Wonderground train pulled away from the cog turntable and back into the darkness of the transport system’s tunnels.
