Hi LM, I greatly missed the Lambeg to Gt Victoria St trains when the family moved to Gilnahirk in east Belfast in the summer of 1958, both steam and diesel, and then on to granny's house at Bloomfield by trolleybus.
I don't recall the UR fire fender in the main waiting room but the fireplace was one substantial piece of work.
I phoned cousin Neill who is eight years older than me, Theo's son, and he was able to provide some more information.
Sammy to whom you refer may have had the surname Wallace. I may have over-promoted Percy Gibson, he was a relief porter from Lisburn. Mr McIntyre hailed from around Armagh and when retired lived in a semi detached house in Harmony Heights area, Lambeg. Prior to Mr McIntyre, the post was held by Bob Campbell. Mr Campbell moved to Adavoyle as signalman when Mr McIntyre arrived.
