The carillon was set up to play automatically or by hand every three hours. There were four barrels, each containing 7 religious and secular tunes. The carillon ceased to play many years ago, since people complained that the sound disturbed them. When the tower was built, the architect considered putting a clock in it. However, he was concerned that a clock might spoil its appearance. In addition, because the clock would be facing Windsor Station, the architect was afraid that, should the clock be inaccurate, he would have to face the wrath of the travelers who might miss their train.

However, the clock was installed and was faithfully on time, losing exactly 6 seconds per year. In an era when the wrist watch had not been invented, and pocket watches more inaccessible under winter apparel, the public clock was of great service to people. The clock was, at that time, illuminated with a 32 to 50 watt candle lamp on each dial. The dials were five feet in diameter and of the best opal glass. It was ordered in 1899 at a cost of 255 pounds sterling. It arrived a year later. It chimes the quarter hours and never less than twice, sometimes more, during sermons at some point! Today, the chimes still ring, but not the carillon. They also ring 20 minutes before both Sunday services. The carillon can be played manually from a small keyboard inside the church itself.
