That will be a Wexford - Rosslare local, probably. The two carriages are green and the tin van filthy "silver", so it's 1958-62 or very close to that. You've a GSWR 1906-era third class coach and a comparatively modern (post-1956-ish) laminate. The loco is as grubby as one would expect..... The cars are (left) a comparatively new (1960?) Austin A35, and what I suspect may be a 1950/1/2 Ford Prefect (right, partly out of sight). A Ford "Thames" (or maybe VW?) van crosses the level crossing behind the train; with all these clues I'm going to say it's definitely 1961 or 1962.
