The Other Railway's High-Speed Trains and Token Girls. Pip and Emma were hired to work on the Other Railway to avoid a sexism lawsuit and remain the only engines to actually run on time once in a while. An easy way to tell them apart - Pip is the sarcastic, sensible one, Emma is the cutesy-poo, ditzy one. Don't judge them by their gender, however - they can more than hold their own in a barney with the other diesels. Also known as Candy and Sugar (by the ignorant Thin Git, anyway).
