Agree 100%. Fond memories from 60s and 70s of loco hauled pax trains, active goods traffic with 2 axle wagons still in use in every little station between Dublin and the other main rail terminals. Intricate track work, loops, crossings and in use sidings in every small station. Hardly a container nor bogie wagon in sight. Best of all interesting traffic movements, loco runarounds, split pax trains, loads of shunting and drop off goods wagons.
A golden era of railways. A far cry from today's boring yo-yo DMUs/ICRs and stations striped of track work. Some no longer even have loops. Still can't stop progress, things have to move on, but we still have the memories and as you rightly say, we now have the ability to recreate new memories.
