The first WCH Electronic Bell, also known as the 0777 bell, was installed in 1998 at Hale Street in Wheaton, IL. WCH E-Bells are still being made today, and continue to use the same design and sound developed in the late 1990s.

One might wonder why WCH E-Bells have different pitches, why some are scratchy and others aren’t, and why some make one long ring at startup. In the 2000s, signalfans came up with  "type" and "generation" systems to explain these abnormalities. However, recent research has uncovered numerous holes in the logic regarding these classification systems. If you want to learn how WCH E-Bells were previously classified, visit here.

Pitch

All WCH E-Bells produce the same sound, albeit at different pitches. WCH E-Bells DO NOT contain a pitch adjustment feature. The variations in pitch are usually caused by slight imperfections of circuit board components during the manufacturing process. However, other factors such as age, temperature, and exposure to moisture can also alter the pitch of a WCH E-Bell.

Scratchiness

The scratchiness of a WCH E-Bell is almost always dependent on volume. All WCH E-Bells have volume adjustment features. While newer WCH E-Bells can be set to full volume without sound distortion, older WCH E-Bells will produce a very noticeable staticy noise while the bell rings. But wait, before you assume this means scratchy bells are their own "type", you should know that newer WCH E-Bells can also become scratchy from aging and exposure to the elements.

Long ring at startup

Originally, WCH E-Bell circuit boards were completely exposed. Around the mid 2000s, a protective cover was added to the circuit board, and a few minor changes were made to the components used. WCH E-Bells with exposed circuit boards make a long ring when they are first powered on. Unfortunately, this cannot be used to reliably distinguish older WCH E-Bells from newer ones, since newer WCH E-Bells can make a long ring when powered on if the ring rate is set to a slow speed.

Ringing speed

All WCH E-Bells are equipped with potentiometers that allow the ring rate of the bell to be adjusted. Starting in the late 2010s, WCH began setting their E-Bells on the lowest ring rate speed prior to leaving the factory. Some railroads choose to speed up the ring rate, while others leave it as-is. Temperature has been known to affect the ring rate of WCH E-Bells. The WCH E-Bell at Taylor Avenue in Kirkwood, Missouri is extremely sensitive to cold temperatures, and has been known to ring at speeds faster than the limit of the built-in potentiometer. It once rang so fast that it became a buzzer bell!

Because of the aforementioned discrepancies in the old WCH E-Bell classification system, there is currently no "type" or "generation" system, nor are there any plans to create one in the future. Despite this, some railfans continue to use the old "type" and "generation" system, so the decision is yours.

WCH E-Bells are popular worldwide, and can be found protecting crossings in the following countries:

• Australia
  
• Canada
  
• Colombia
  
• Ecuador
  
• Ethiopia
  
• New Zealand
  
• Portugal
  
• United Arab Emirates (UAE)
  
• United States
  
• Venezuela
  

All WCH E-Bells are designed to fit on 4 or 5 inch diameter poles.

All WCH E-Bells function on 12 volts, and can function on both AC and DC.

Current WCH E-Bells can produce sounds between 80 and 90 dB at 10 feet away. Older WCH E-Bells (such as the one formerly located at Gore Ave in Webster Groves, MO) could be jerryrigged to exceed 100 dB at 10 feet away. The one at Gore Ave measured a whopping 115 dB while standing under it.

WCH E-Bells measure 18 1/4 inches in height and 6 1/2 inches in diameter.

WCH E-Bells weigh about 10 lbs.

The retail price for a brand new WCH E-Bell is $425.00 USD as of August 21, 2025, according to Hybrid Bell.
