Talk:Whistle post

Sentence fragment
 Generally, even if the advance warning provided by the horn will be less than 15 seconds in duration.

Does this fragment go with some sentence or clause that has been deleted, or does it go with one of the sentences before or after it? It doesn't seem to make much sense when connected to either. 69.42.7.212 (talk) 03:44, 19 April 2009 (UTC)

Whistle posts now?
Are there whistle posts now, or automation, or both? Different by country?--DThomsen8 (talk) 15:08, 24 April 2016 (UTC)
