Gudok (short story)

Summary
Tegan and Turlough are stuck in Vladivostok, 1904, by a teleportation accident. They take a first class sleeper on the Trans-Siberian railway, aiming to meet up with the Doctor in St. Petersburg. As the train leaves the station a young man dies under the wheels of a train on a local line. Tegan and Turlough are travelling with a civil servant named Sasha, who tells them that the dead man was a friend of his, a party to a message that only Sasha can now deliver. Tegan begins to suspect that other passengers on the train are enemy agents.

Three days into the journey (and still two days away from their destination) Sasha is murdered as the train crosses Lake Baikal. Tegan considers the possibility that Turlough may have been responsible for the murder but begins to trust him more when their room is ransacked. Working together they set a trap for the real murderer, the train's steward Rodya. As the train arrives in St. Petersburg station, Rodya tries to escape, but is apprehended on the platform by the Doctor. Tegan decides not to take the scenic route in future
