I've noticed a very subtle difference between modern WCH Gate Mechanisms and older ones, like from the late 80's-2000's.
The older mechanisms seem to have a smoother curve to them, compared to the newer ones that have sharper design.
Here's an example of what I mean.
Older Model: https://www.google.com/maps/@25.8417235 ... 384!8i8192
Newer Model: https://www.google.com/maps/@25.8422374 ... 384!8i8192
I'm not sure if this is just a different series all together, or an modernized version of an already existing model. I do know that these have been around since the 70's, being in production under the Federal Signals brand until WCH was formed. It may just be a slight cosmetic change, but it's been something I've wondered about for a while.
I couldn't find any information about this change anywhere else, so I hope someone can enlighten me here. :)

Re: Question about WCH Gate Mechanisms
I wonder if it was changed when they changed their light head molds.

Re: Question about WCH Gate Mechanisms
They probably got changed around the time they changed the design of the counterweight arms.
They/Them for me, please.

Re: Question about WCH Gate Mechanisms
I think it's mostly just for freshness I don't think any of the internal parts have changed but you can check WC Hayes website. They have some videos of the older mechs and diagrams of the newer ones.

Re: Question about WCH Gate Mechanisms
There are some changes with the newer ones, that I believe were federally mandated, such as the EGM cards (as the Safetran S-60s also got these changes).JosephTrains wrote: ↑Wed Jul 24, 2019 10:33 pmI think it's mostly just for freshness I don't think any of the internal parts have changed but you can check WC Hayes website.
