Click on the buttons to listen to the chime. Selecting another chime while one is playing will stop the chime that is playing before playing the chime that you selected. Fun facts: -The DTL chime is just the NEL chime but faster. -The old SMRT chime is still used by the R151, C830 & TEL trains.
Easter egg: To be found (Tell me in the comments what is it and how + no looking at the code) Credits to @snhyper for the sounds
