Work and Events / Re: What If? Design Project: 1925-1940 2ft Diesel
« on: January 31, 2018, 09:51:49 AM »
Rob,

If you are thinking of wheel centers with spokes, I made patterns for two sizes which are currently stored at the railroad.  Depending on the thickness of the tire or how much is machined off the center, you could go from a 18" wheel (like on the Model T railcar) to a 20" wheel (like on #11's lead wheel assembly), or even more with thicker tires.  With the larger center you could start with about a 31" wheel or larger depending again on the thickness of the tire.  I don't know if you are thinking this large a wheel, but it is remotely possible.  At this point I wouldn't offer making a mid size pattern because of the many pattern projects I have to complete and based on #11's time line, this project would be ten years away before it was physical consummated.

If you are thinking side rods and cranks with the larger wheel center, the patterns for the cranks are also made and in storage.

I have seen mine locomotives where the traction motor was mounted longitudinally between the axles with worm gears.  You could possibly use truck differentials with some of the gears removed for this.

Rob,

Why don't you study what the Mount Washington Cog Railway used to make their diesel-hydraulic locomotives?  I believe they used a standard power unit with hydraulic motors.  I know it was unsuccessful on the Southern Pacific and Rio Grande for various reasons, but on a small road like the WW&F it may be the simplest way to go.  I am not a mechanic, so this is just a "from the hip" suggestion.

As far as the aesthetics of the locomotive, make it look good . Design it with AAR type trucks with drop equalizers like passenger car trucks similar to  those used on road switchers.  The Durango & Silverton made a beautiful self propelled car and put it on what I feel was a very cobbled looking front truck made from an industrial locomotive.  It looked terrible.  Home made locomotives tend to look cobbled up.  Try to avoid that.

Alain,

Thank you for the information.  I went to the two areas you recommended and learned more.  Unfortunately I could only appreciate the photos at the web site because I cannot speak or understand French.  I am looking forward to any more information.

Alain,

Could you tell us about the railroad?  I Google mapped it and traveled the whole length from the terminal to the loop.  What is that loop area all about?  It is a spot of trees in the middle of fields.  Was it something else before this became a heritage line?  Was the line longer at one time? Were there branch lines?  Is there a map of the line if it was longer?  What was it built to serve?

I think the Rhine's cats are spoiled by living in a super environment.  I don't think they would want to spend time in a dirty shop.

Museum Discussion / Re: Are wood patterns obsolete?
« on: June 16, 2017, 07:18:52 AM »
Paul,

I have a pattern for a yoke which will accommodate a 13" diesel bell which I made many years ago.  If you PM me your email address, I will email you photos and dimensions, but it is probably too small.  I do not have the desire or time to make one, but if this would work, I would loan it to you to get cast.

The yoke for #11 is similar in size. 

The Cattail Foundry may have the pattern or even what you want in stock.  Again, if you PM me, I will give you their phone number and explain a few things about how they do things.  It is an interesting place.

Museum Discussion / Are wood patterns obsolete?
« on: March 31, 2017, 09:22:46 PM »
On Wednesday I visited a modern foundry with a pattern for CNJ 113.  It is yet possible for them to do one off wood patterns but was informed basically that they were not really interested in that type of work or not using wood patterns.  What they really wanted was a computer disc where they could 3D print the sand molds and cores.  One of the people I talked to suggested that if I wanted to save costs would be to get some knowledgeable volunteer with access to the proper computer to write the program for the part.

He also went on to say that their pattern shop did not make patterns anymore, just did repairs and modifications.

I know that Jason is fully cognizant of the process of 3D sand mold printing, so what I am saying is not new to him.  What I am leading to is this:  is it really necessary to make wood patterns for our locomotive 11 project if they are going to be used a few times and then forever stored and never used again?  I am hoping that the currently finished patterns made by Allen, Howard, and myself will be used but if we wait too long, will they be obsolete?  

On my visit to the foundry, I was showed the machine that did the 3D printing and a large mold that was just done.  Even though I was aware of the process, I was shocked by the precision of the mold.

I was just wondering if it would be better and cheaper and more time saving if we just went totally to the new processes to get our parts cast.  Probably the only foundry that I know of that will probably continue to use the old methods is where Wayne got the castings made at the Cattail Foundry.  Their choice of metals is somewhat limited.

Any more thoughts?

Bernie

Edit:  It's been a while since I started a post.  I wasn't paying attention to what I was doing.  Thanx for moving it.

Can anyone tell me where the old fashioned light shade assemblies in the shop were purchased?  We would like to purchase some for the Minersville Station canopy.

General Discussion / Re: Miller Hook Couplers

Marcel,

I believe the Rhinelander Logging Museum has a business car with Miller Hooks.  I saw a picture of it and if I recall where I saw it, I will write it up here.  You can reach their website through a general search mode.  I don't know their hours, but it said it was closed today.

Some things that have not been mentioned yet are:  it is my belief that if the FRA really wanted to regulate the WW&F and had the personnel to do it, they could.  If there was a serious enough accident on the railroad guess who would probably investigate.  The railroad carries passengers and I believe that could qualify for FRA oversight.  So far, in some cases, their concern is about the use of steam locomotives.  Someone could add more to this point.

Keith's mention of the wooden underframes being obsolete should bring into consideration that all NEW construction for passenger carrying cars should be built with steel underframes and a welded tubular body frame the way it is done on the WP&Y, across the pond on the many tourist lines in the UK, Puffing Billy down under, etc.  Many of the narrow gauge railroads in these areas had steel underframes under their new cars around the turn of the last century.

The unguarded crossings on the C&TS and on Joe's daily travels have been there for more than 100 years and have been grandfathered in by time.  Most people who live in these areas have lived with these crossings and are generally aware of what is moving on them.  Again, there are people out there without a clue.  Several years ago someone PARKED on the R & N's mainline crossing near my house.  "Oh, I didn't think those tracks were used anymore".  I generally do not stick my nose in things, but I felt compelled to tell her about the danger.  Fortunately, she listened and moved her car.  Less than 15 minutes later a train came through.

Something that has to be taken into consideration is that the crossing at 218 is of NEW construction and that has a whole new set of parameters than something that has been grandfathered in.

I don't understand this scenery thing.  When people drive to the railroad they see all kinds of woodsy scenery, the ocean, quaint towns, etc.  The railroad only offers trees and fields.  Touring the shop is fascinating, but how many people do it?  People come for the riding experience on an olde tyme railroad or just for the fun of riding behind a choo-choo.  When Joanne & I rode the dinner train at Wellsboro, PA, the scenery didn't do a thing for me compared to looking at the nearby "Grand Canyon of PA" scenery which I had to drive to.

Bill, after our experience of a few years ago, your 2 cents is worth $1,000,000,000.00 to me.

I do not understand why people would want the railroad to cross Rt. 218.  It would increase the ride by about 4 minutes time and once you get beyond the "cut", the fill is cut off by a road which is several feet below the level of the roadbed and someone's depressed back yard is beyond that.  If there was the remote possibility that several more miles could be built beyond the 218 crossing then it could be worth it.

I believe that when the railroad reaches the 218 crossing, the railroad will be long enough to satisfy the average tourist.  Also, track maintenance, especially on the hill is going to be considerable.  Will the next generation be willing to do that kind of work?  At what point will the railroad reach when only all the work will be just maintenance and there will be no time for building.

As far as traffic goes, it takes only one of Wayne's yahoos to do considerable damage.  On our trips up to Maine, he has discussed some of these incidents.

Kevin,

Who thought that such scenes would be available in 2016?  Your stuff just goes off the charts and your willingness to share with us who don't get to these events is just mind boggling.  Keep it up.

A friend found this on Ebay:  #112055914822 OLD MAINE MAP BOOK: MAINE CENTRAL RAILROAD TRACK SMALL TOWNS PLAT LAND OWNERS.  Even though most of us know the track plan at Wiscasset, this is the official document.  I have no part in its sale.
