Agreed. I also much prefer the traditional bell sound. The Desiro buzzer is even worse; a truly pathetic sounding thing.
Yes the worst one is on the Desiro City trains. Much louder than the original Desiro trains. The beep sound on the Desiro City is the loudest ear piercing beep i have heard of any trains. It is as loud as the door release sounds. It also plays throughout the entire train at every single door panel.
Sadly it seems like we are moving away from using bells. Electrostar trains are the only trains built since privitisation to have a bell on them. Everything else is just beeps these days.
Maybe it is just nostalgia from working as a Guard on old slam door EMUs and DEMUs but i always thought bells work the best. It is the clearest sound. Unlike beeps and buzzes it can not really be confused with any other sound you might hear on the train or at the station.
Another question regarding bells. Does anyone know what was the first train in the UK to have bells or buzzers or beepers. Originally all trains just used flags but i am presuming it must have been one of the very early multiple units in the mid 1900s or maybe slightly earlier.
