Have anyone here heard of the Frogless Switch ? Found a short write-up on the switch in the July 1920 issue of the Electric Railway Journal. I have the pdf version downloaded onto my iPad under the Google Play app.

The switch was developed by the Walls Frog-less Switch and Manufacturing Company of Kansas City, Mo. It is operated by four bell-cranks connected to two rods operated by a switchstand. The model version could get by with an lever arm connected to a switch rod.

I am going to try to either post the article mentioned or have photos of an operating scale example. It looks pretty straight forward.

If you look at some of the old switches for cheap toy train sets, you will see a way of even avoiding what appeared to be a movable "point" in the frog of the switches in the photo.

In Philadelphia, around the turn of the 20 century there was a trolley line built around Fairmount Park, which I think was the largest municipal park in the world--might still be. This lines primary purpose was for citizens in the area to "take the air" on steamy summer nights in open bench cars. An amusement park was built along the line, and was a moneymaker for the trolley also. By the 1950's the lines purpose had drastically diminished--and the original cars--open ones for summer, closed for winter (when there was hardly any traffic) were showing their age, and the whole thing was scrapped--now only a walking trail through the park--with an almost guarantee that you can get mugged in broad daylight. The "City of Brotherly Love" at it's finest.

Off the .

When built, the switch to get off the main line and into the car barn was made so that the diverging rail was lifted up over the straight rail at the spot where the frog would have been--this was done so that there was "no bump going over the frog"on the main line. There were other conventional switches on the line, however, so it is my opinion that the frogless one was provided by the inventor so that he could claim that the line used his invention. It continued to the end however. Although I rode this line as a kid, the carbarn was in a remote area (still exists, and serves as storage for park maintenance equipment) so although I rode over the switch many times, probably never knew that it was there--or its purpose. I have never seen a good photo of the switch, to see how the ramp part moved or worked. Must have been something that was only taken on the first point--the minimum speed on the controller.

I was thinking a "frogless" kick-switch, mostly used for 18" gauge mine railways. I have one on my 15" gauge slag dump line at the smelter. If anybody is interested, I can take a photo and post it. There are some prototype photos of these taken by Charley Lix in several of his posts here (I just don't know where..) The one shown above is "mui complicado"...

Frogless switches were installed on the Penrhyn Rly (N Wales) almost 200 years ago. A short length of rail, about 14" long, could be fixed by hand in one of two positions - straight or diverted. I have photos but they are no longer compatible with the FR Gallery system.

Regards, Michael

Hi Michael :wave:

If you have checked your 'right-click' as we spoke about...
...& don't see a 'resize image' option, I can send you a piece of software that will simply resize any of your pictures.

Everyone else on Planet Earth seems to be able to resize their damn happy-snaps, except your good self ! ;)

Si.

Look back later folks !
Tomorrow I'm giving away FREE laptops & Cup Final tickets !!
