This mural by artist Paul Aloisi was painted on the railway underpass at Davenport & Dupont in 2014. Its title"Synesthesia" refers to the phenomenon where the stimulation of 1 sense leads to experiences in a 2nd sense - here it is hearing and vision. The mural is meant to be a visual representation of the sound of trains passing overhead. If you have time check out his site (HERE) with a short youtube film - it's pretty cool.
