Mike's Railroad Crossing Forum

Does anyone know when UP stopped installing mechanical bells (If they ever did) on new railroad crossing signal installations? I know one of the crossings nearby me that was installed in around 2006 or 2007ish uses two WCH 0333 mechanical bells when most installations done by that time in my area all used WCH electronic bells. This is my first post here and it's the first time I've used a forum so some advice would be helpful. Thanks.

I believe it was around 2007-2009.Before that, I have seen a lot of WCH M Bells on installs through youtube videos, not in person, cause I lived near Norfolk Southern tracks.Now today I live Near UP tracks, and most crossings in my town that are UP, have WCH E Bells. I hope this answers your question.
