Tuneful Toots

S9, E8: Rusty is so excited to give the brass band a tour of the hills that she loses track of time! Half-way across a lake, she runs out of diesel-oil. The band worry about missing the concert. Rusty tells the band to play loudly while she toots her horn! The Fat Controller, Mr Percival and the other engines hear the music and puff up the track to hear the band play!
