If it is a SIGNAL SOUNDS tender, then Whistle and Bell are the ONLY sounds that tender will have.
a TRAIN SOUNDS tender will have Chuff, Whistle and Bell, But ONLY ONE SOUND at a time. While running a TS tender will Chuff, if you ring the Bell, the bell will override the Chuff, and the Whistle will override Chuff or Bell.
a RAIL SOUNDS tender is a Sound on Sound system, where the Bell will ring with the Chuff still in the background, and the Whistle blow with the Chuff and Bell still working.
if it IS a SIGNAL SOUNDS tender, it doesn't sound like there is anything Wrong with it, you are expecting more from it than it does
