Occasionally there are discussions here about authentic types of locos and rolling stock for preserved lines. As a non-expert casual enthusiast (with a narrow gauge bias) I don’t actually know what a typical passenger (or goods if you like) train would have been on the various heritage lines before preservation and would be interested to know. Maybe pre- and post-war (or boom years and decline....). Typical may be hard to define, I imagine seaside lines for example would have had quiet winters and different workings on a summer Saturday. Feel free to say whether the line in question has the current ability to run a typical train, or close to the same spirit without having exactly the same classes, but hopefully keep the thread as a record with no controversy or criticism of non-authentic lines, I don’t mean it as a competition!
