A Coarse Guide to the Steam Locomotive for ‘N’ Gauge Modellers

A short addendum about snifter/snifting valves.

By no means all superheated locos had them. Some had them for only part of their life.

The LNER used them extensively; the SR used them but were later removed.

See

https://en.wikipedia.org/wiki/Snifting_valve

for a better explanation than I gave!

 I'm surprised that our friend John@trainfish has not commented on this as he has been known to enjoy a snifter from time to time ?
