As part of my 20 years in Ireland/201 numerical retrospective, I’ll offer just a couple views of Irish Rail 203.
My memories of this engine are largely the blast a horn and the rush of air as it passed with Mark 3 carriages in tow on the Dublin-Cork line.
One instance stands out about the others though: I was showing some American friends around the island; we’d borded the Cu na Mara Mark3 international set at Heuston behind locomotive 215 destined for Galway. We got as far as Hazel Hatch, when 215 coiled up and we were sent into the loop to await a rescue loco from Inchicore.
Guess which engine was sent to bring us to Galway? (This is not a trick question).
