Your five senses are amazing things! It's incredible to think that a simple smell can invoke a childhood memory and a taste can bring you right to a certain point in time. But what about one's sense of hearing? I strongly believe that it is just as powerful. Many times, the sound of crashing ocean waves, bird calls, and regional accents have reminded me of specific instances in my life. In Massachusetts, another sound sends me back to my college days in Boston. While not as relaxing as birds chirping or waves crashing, this noise is certainly nostalgic.

Before you read the heading, close your eyes and hit play on the video below.  Can you identify this familiar Massachusetts sound by just listening?

If you said the “T,” then you guessed correctly!

It’s hard to mistake the squeaky sound of the wheels as they run along the tracks, the creek the cars make as they turn within the tunnels, and the highly recognizable noise the train makes as it breaks to a stop.

If you have lived in the state for a while, you probably know that the country’s first subway system was invented in Massachusetts. This revolutionary transportation phenomenon took place way back in 1897 with the opening of the Tremont Street subway.

This is what the Park Street station looked like when it opened in 1898.

The “T” now has five different color-coded lines. The system includes over 150 stations that serve greater Boston and the surrounding area.

It now hosts millions of riders each year and is currently one of the busiest subway systems in America.

And the noise of the train car isn’t the only “T” sound that invokes Massachusetts nostalgia. If you are of a certain age, you may remember when stops were announced live or when Frank Oglesby became the recorded voice of the Red Line.
