MLSS is a charity based on the Sikh principle of dasvand, which involves giving 10% of your time and earnings to help those less fortunate.
Mr Singh added: “For many people, the festive season is not a time of joy but one of deep loneliness, isolation, and despair.
“We know that suicide rates rise at this time of year, and for those with no family, no home, and no-one checking in on them, Christmas can feel unbearable.
“We are there to serve them, to listen, to show care and compassion, and to make them feel truly special.
“In our eighth year working with Network Rail, this meal represents everything we stand for at MLSS: Dignity, equality, and the belief that no-one should feel alone.”
