Ada, Jane, and Mabel are three Narrow Gauge coaches.
When Skarloey returned, Peter Sam showed Skarloey around. Peter Sam later met these three coaches and a brakevan; he soon took Ada, Jane, and Mabel for the train at the Narrow Gauge Station where Henry was waiting.
Ada, Jane, Mabel and Cora were pulled into the Narrow Gauge Station. Henry had waited; the passengers cheered when Peter Sam pulled the coaches into the Narrow Gauge Station.
Sir Handel prefers the three as "cattle trucks" which make them angry.
