Henrietta is Toby's faithful coach, who likes to be full of passengers and take them on journeys. She does not like to be separated from Toby, although she rarely carries a full load of passengers. Henrietta acts as moral support for Toby and in return, Toby does anything he can to help keep her in service. "She might be useful one day." he says. Henrietta also has a sister named Hannah.
Henrietta is based on the GER Wisbech and Upwell Tramway 4-wheel coach.
Henrietta is painted brown-orange with red bufferbeams and a grey roof.
