Throw Back Thursday – PROCOR Pressure Flow Cars

Often mistaken as some type of modified tank car, Procor built ‘Pressure Flow’ cars were in fact constructed to an AAR Tank Car Manual prescribed specification; AAR 207A. Per most pressure vessel guidelines, operation above atmospheric pressure (14.7 psi) is subject to an industry issued code or standard. As example, boilers are subject to ASME pressure vessel codes, while steam locomotives are subject to DOT 49 CFR Part 230. Procor built Pressure Flow cars had an design/operating pressure of either forty or forty-eight psi. 

Over a thirty-year period, between 1965 and 1995, Procor Oakville constructed more than five hundred Pressure Flow cars. Predominantly used in powdered cement transport, the higher pressure rating provided for over packaging of more volatile materials such as calcium carbide. Calcium carbide is used in steel making and in the production of acetylene and reacts violently when exposed to moisture. While also manufactured to support it’s lease fleet, most Pressure Flow cars were built under contract for sale to others. Sale customers included British Columbia Railway with thirty, Canadian National Railways with more than three hundred and Canadian Pacific Railway with more than one hundred.

Today, only a handful of Pressure Flow cars remain in service. Cars constructed in the 1960’s and early 1970’s were subject to the AAR forty-year interchange life limit. Powdered material transport migrated to conventional Class LO covered hopper cars equipped with low pressure rated pneumatic off loading apparatus. The last Pressure Flow cars constructed by Procor (UTLX 800000 – 800007) were built for the Union Tank Car fleet for use in Phosphorous Pentasulfide transport.

East Deerfield, Ma

Mid morning at East Deerfield May 3, 2026 

I have been to East Deerfield many times but this was the first time I saw someone using the B&M caboose near the bridge. I was watching over the other side of the bridge when I could smell something burning. Guess it was stove oil. When I walked over to the other side I was surprised to see smoke coming out of the chimney. I guess it is someone's getaway location on a cool Sunday morning...George Dutka  

CN Woodchip Cars

My CN operational diorama that I was working on in the late 1980's has an Athearn geep shoving a cut of woodchip cars I kitbashed from Front Range boxcars. The caboose was scratch-built by Al Howlett back then. I believe I purchased it off Bob Hannah. Wish I kept it to compare to the new ones coming out soon.

I took this photo back in 1989 of a 12' diorama I operated on. I recently found the slide again and scanned...George Dutka

New Haven Depot

I stopped by the New Haven depot which has been moved to Bristol, Vt. a short distance away. It is located next to the library and town office. There is a new base to the structure, stone and concrete. Maybe a basement will be included inside or that is a pad it is on. It seems higher off the ground than it was in New Haven. The roof has been replaced but there is still a lot of work to be done before it can be used...George Dutka

Proto CP Paper Car - Part Two

The finished model with some light weathering on the side. I wanted a clean looking car but used.

A few more views and what the roof looks like...George Dutka 

India ink and alcohol is brushed on the roof.

The roof once it dries. Seen below is some PanPastel raw umber shade brushed on and a light coat of AK railroad wash...very lightly.

The car is lightly weathered using PanPastel Paines grey extra dark along the top and bottom portions of the car and some Bragdon dark rust as highlights on parts that move or get beat up. I also added some chalk marks and a placard board note.

Proto CP Paper Car

The finished model with all the ladder, door hardware and brake wheel attached. I also added hose bags and Kadee couplers to the model. The weathering was kept light on this model.

I finally got around to working on my CP Proto 1000 paper cars. I have two on the go. One is from Peter Mumby while the other I purchased from my friend Chris Wright which unfortunately was missing the ladders, brake wheel and door hardware. I need to dig into my stock for that stuff. Captions tell the story. More on this car tomorrow...George Dutka  

My two Proto cars as they look at the beginning of the project. I had already done the roof on one about a year ago for an RMC article.

The underframe is given a coat of AK railroad wash followed by the rust tone included in the three package while still damp. Some AK light rust is also applied at the end.

The two products used on the models underframe worked out well with little effort. You saw how I did the trucks and wheels in last months This and That.

Throw Back Thursday – RS18u OSR 181

by Keith MacCauley
Ontario Southland Railway No. 181 was constructed by Montreal Locomotive Works for the Canadian Pacific Railway in May of 1958 as RS-18 CP 8777. In 1989 the veteran unit entered CP’s remanufacturing program emerging as RS-18u CP 1861. Cast off in 1998, the unit was acquired by OSR and shortly thereafter decorated in the railway’s attractive maroon and cream scheme. The venerable unit has been out of service since August of 2021 due to electrical issues, and having been sold to the Sartigan Railway, now calls ‘La Belle Province’ home. 

For several years the Elgin County Railway Museum located in St. Thomas held an annual August Open House I believe called ‘Railway Days’. Over the years it was possible for the host to attract visitors to the event as the museum benefitted from a connection to the outside world via CP (since severed). In addition to OSR 181, among other attractions, I recall seeing a Canadian National GMD-1, ETR No. 9, and a brand new Union Pacific SD70M from the nearby GMDD locomotive plant.

Despite several Railway Day visits, I do not recall ever seeing Peter Mumby at the event. However, it seems that Peter and I were both at the Museum on the same day some twenty-seven years ago. Not only were we both there, but we both took almost identical shots of No. 181! While the timing of my view appears to be more high noon, based on the lighting, Peter’s photo was taken later in the day. It does appear that No. 181 has moved a couple of car lengths as well. Small world!

Touring VRS North Walpole NH Roundhouse

The group is seen inside the roundhouse as Aaron Bridge the Superintendent of railcar repairs in North Walpole (blue hat) fills us in on their operations. May 3 2026.

On Sunday the RRHS convention group gathered at the VRS roundhouse across the river from Bellows Falls yard and station. It was an interesting tour as I have never been on the grounds of shop and yard so this was a treat. These days the roundhouse is used to repair rolling stock although I noted a coach being stored in the end bay. 

I thought we could wander over the whole property but we were restricted to inside the roundhouse and around the turntable. The engines were all stationed further down that was off limits. The VRS has a nice display of signs they have saved which was nice to see...George Dutka

The entrance we used.

One of the original signs from Steamtown is seen on the wall. We were told this was found hanging on a locals fence and was salvaged to be saved inside the roundhouse. May 3 2026.

Inside the roundhouse there is a lot of stored stuff and neat artifacts on the wall.

Around the turntable.

Two railcars requiring service.

Stencils hanging on the wall.

A piece of rolling stock seen in the last stall of the roundhouse.

Bellows Falls Models

A few more views of Ray Muntz Bellows Falls models. Unfortunately the chain broke on the ball signal he brought but it looked good. I still need to build the signal shanty for my layout. Another project to look into later this year. 

The sand house is a lot bigger than the Rutland Car Shops version I used on my layout. I learned at the convention the sand came from Alburg and was hand loaded into the sand house which would have taken a good amount of time. I think in later days some type of compressed air was used...George Dutka

The Rutland Ry Historical Society Convention

Two thirds of the Bellows Falls convention is over. Today we are going to the B&M roundhouse before I head for home. Friday night was a nice surprise. Most of the group went to diner at the old CV Windsor, Vt. station which is a very nice restaurant. They make their own pasta. Chicken parm. was great although it all looked good to me.  I would recommend dinner here. Back to the Best Western hotel in Springfield for slide night.

After elections Bill Badger gave us an update on membership which is down to about 200 from 400 years ago. He mentioned that today the average age of members is pre-deceased. That got some chuckles. Laz is working hard on getting the Newsliner back on track. An issue should be out shortly.

The days presentation were good. Phil Jordan covered the Bellows Falls switcher, milk business and roundhouse scene. Next up Bill Schultheiss did an overview of 24 hours in Bellows Falls in 1952. He counted on most days 44 trains came into town. I can only imagine railfanning there then. In the morning it seemed there was a train coming or going every 15 minutes with sometimes two there at a time. That is not counting the local switchers or trolley. Bill is modeling Bellows Falls and did a wonderful job researching this location. After lunch Phil covered the trolley scene, then Laz covered the flood of 1927 in town. I left after that as I felt tired and maybe overwhelmed with all I learned. There was only one more clinic left. It was great to see everyone. Some I had not seen in decades...George Dutka

I guess train time at Windsor station is now beer time.

One table full at the Windsor station restaurant. There was three full tables with the last ones arriving sat at the bar.

Ray Muntz Bellows Falls model. An article on this model and plans were in a past Newsliner.

Lots of Rutland papers for sale and books.

Don had some Rutland brass for sale.

The day began with a short business meeting. Left to right is Phil Jordan, Bill Badger and Laz.
