The orange hoodie, of course, indicated Team Orange. Curufin would explain about the teams if he was asked.

"Unfortunately, the train entity doesn't tell us that. I wonder why? In the bureaucracy of the Void, the Voidtrecker Express is considered to be a rogue transport, that is, not registered with the Ministry of Void Travel, though known to it. Maybe not asking our permission has something to do with not wanting to set up a system of recruitment and risk being more visible and maybe getting nailed by the Ministry."

Curufin nods. "It seems the train picked the right day, when it collected you. And it's true you're not unique in that you would have agreed had you been asked. I would have, too. But in my case, it was the other way around -- I asked the train to pick me up."
