Golly! Dramatic ending tonight, with a train crash right next to Nonnatus House, and with Dr Turner, Sister Julienne and Nancy on board! Doc T and Sister J may be gonners! A slightly unlikely scenario, though, I'd've thought - the crash was caused by the driver having what appeared to be an epileptic fit, and in that case, he'd've let go of the dead man's handle, and the train would''ve stopped automatically. I'm sure they had DMHs in 1967.
