Transport for Greater Manchester joined Manchester City Council, Network Rail, rail operators and British Transport Police as the country fell silent to mark the centenary of the start of the Battle of the Somme.
Reverend Nigel Ashworth led a short service at the war memorial at Manchester Piccadilly this morning, with the Last Post playing across the station and preluding a two-minute silence.
Its first day of conflict remains the bloodiest day in the history of the British Army.
Wreaths were also laid at Oxford Road train station, Rochdale Interchange and the First Bus depot at Queens Road.
Later today TfGM employees who have previously served in the Armed Forces will take part in a parade through the city centre – one of a number of commemoration events being held across Manchester.
Dr Jon Lamonte, said:
It is difficult to properly comprehend the brutality that started 100 years ago today and went on to last 141 days. More than one million people were killed or injured during the Battle of the Somme. Young men – brothers, sons, husbands and fathers – paid the ultimate sacrifice in defence of our country and it is extremely important that we remember them.
