Review for LEGO set 7710 Push-Along Passenger Steam Train from Brickset
Nice little starter set — “This set is a basic entry into the grey era train system. Especially the locomotive is really basic, while the two passenger cars are nice and offer good playability. When the new system was introduced in 1980, this was the smallest train starter set available. But this... More doesn't mean that it was cheap - the price was within the range of bigger technic sets like the Unimog 8848.”
