The Great Western Railway Girls

September, 1939. When war is declared, Lily sees an opportunity to escape her domineering father: she will join the Great Western Railway factory to win her financial independence and move out of home. Maggie doesn't want to simply follow in her sisters' footsteps and work in the laundries at the GWR. So, when the chance comes to volunteer for mens work in the machine shop, she's the first to raise her hand. Catherine, a clerk in the GWR office, has been helping with London's evacuation efforts, organising trains to move children out of the city. But when her task is completed, will she defy her family and fiancé's wishes and sign up for a more dangerous role? Taking on demanding new duties, Lily, Maggie and Catherine - and others - develop an unexpectedly close bond. But will friendship be enough to carry them through the ups and downs of life at war?
