I was under the impression that it is mandatory for the sounding of train horns to use both tones in most circumstances, to differentiate the warning from, say, a road vehicle. However, I rarely hear both tones used these days, and on my line the many 'W' signs for crossings only elicit a single tone.
Have I missed a rule change - is this now permitted, or am I wrong in thinking that two tones have always been required?
You're onto something there. Traditionally, using both tones for train horns helps distinguish them from regular vehicle sounds, especially at crossings. While it used to be a standard practice, there might have been some changes or regional differences in enforcement over time.
If you're noticing a shift towards single-toned horns, it could be due to updated regulations or evolving practices in certain areas. Sometimes, specific guidelines might vary, leading to these differences in usage.
