"We quickly cut off the power supply to protect the equipment and rolling stock and ensure the safety of the customers, and the leak was then plugged," said the STM.\nService on the orange line reportedly resumed shortly after.\nBut the light at the end of the tunnel was the hilarious responses that came about on Twitter about the "Lionel-Groulx waterfall."\nOne Twitter user decided to write a poem about it. "The Lionel-Groulx waterfalls are one of the great nature spot in our city. Look at this disgusting brown water falling onto the metro, seeping through the cracks. Feel its dirty drops on your skin."\nAnother wrote, "Vivre le titanic au métro Lionel - groulx" — an ode to everyone's favourite movie.
