That’s great to hear the m bells have been left alone, especially the teardrops.McK&H.Aust wrote: Sun Jun 02, 2019 8:11 amThat is certainly the theory behind bell maintenance but from speaking to a couple of signal maintainers in the past, I could add the Australian procedures for mechanical bell maintenance (well NSW anyway). I think it really depends on the enthusiasm of the local signal maintainers for the crossing concerned.freebrickproductions wrote: Sat Jun 01, 2019 3:14 am Mechanical and electronic bells all operate off of similar voltages, usually somewhere around 12VDC. The main advantage of e-bells over mechanical ones is the lack of moving parts that have to be maintained.
Here's what all needs to be checked & maintained in a mechanical bell:Meanwhile, with an e-bell:
- Gong (rotation every so often, replace as needed)
- Hammer (replace as needed)
- Hammer mechanism (parts oiled and replaced as needed)
- Electromagnets (replace as needed)
- Wiring (replace as needed)
If you do all of the above, in theory, you could keep a mechanical bell running forever. However, almost all mechanical bells ain't made anymore, so you'll likely run out of parts eventually.
- Does it sound? If not, replace.
Also, electronic bells are much lighter and tend to be a bit less bulky than mechanical bells, which makes for a huge difference when trying to lug one up and down a ladder.![]()
1) If it works, leave it alone.
2) Very occasionally, open up the bell door and clean out any dirt from inside. Apply some bug spray around the gong.
3) If it doesn't work, have a play around to see if you can get it going again. Replace if needed.
While on the subject of mechanical bells, I just returned from a weekend away in the Lithgow area and have some good news for a change. It turns out that the crossing at Rydal which I thought was going to be upgraded, hasn't actually been upgraded yet and still has the same m-bells https://www.google.com.au/maps/@-33.481 ... 312!8i6656
Also discovered that this crossing at Portland actually has a Federal Signal bellhttps://www.google.com.au/maps/@-33.357 ... 312!8i6656
It's pleasing to report that none of the other m-bells in the area have been touched and all of these crossings still have the same bells:
Bundarra St, Blackheath https://www.google.com.au/maps/@-33.635 ... 312!8i6656
Geordie St, Bowenfels https://www.google.com.au/maps/@-33.478 ... 312!8i6656
Oakey Forest Rd, Marrangaroo https://www.google.com.au/maps/@-33.451 ... 312!8i6656
Pipers Flat Rd, Wallerawang https://www.google.com.au/maps/@-33.410 ... 312!8i6656
Portland Cullen Bullen Rd, Cullen Bullen https://www.google.com.au/maps/@-33.300 ... 312!8i6656
Also, going by recent videos and pictures of crossings on the Eyre Peninsula Railway, all Incandescents have been replaced with Westinghouse/Invensys/Siemens 12 inch LEDs, and all Mechanical bells have been replaced with Safetran Type 3 E Bells
Also if you take a look at my Top 10 favourite Ad Met crossings video on YT, a fellow Crossing fan in SA by the name of vacbag recently went to the NRM and they got permission to go to an out of bounds bell pile, which apparently had some very rare bells including a Bryant Zinc co bell, Cast Iron Mck&h Teardrop Bell, Westinghouse Teardrop bell, and a US&S first generation Teardrop.
