Hey gang. So what’s the triangle thing called that’s at the lower front of a locomotive. Is it a snow plow or a cow catcher ?.
the correct term is pilot.
It’s called the “pilot,” although popular parlance uses cow catcher. Not all pilots are triangle things – simple footboards are also pilots, and some pilots in the late steam era were not really triangle shaped either, such as the front of the Big Boy.

PS (edited post): Mark Twain told the story of being on a train so slow that he suggested to the conductor that the cow catcher should be taken off the front of the locomotive and be put on the back of the rear coach, because “at the speed we are going we aren’t going to catch many cows, but there is nothing to prevent them from climbing up the back steps.”

Well it depends on the pilot design too… Some pilots are really just footboards. My local steam engine display has a set of footboards with a small cowcatcher below the coupler: http://www.steamlocomotive.info/vlocomotive.cfm?Display=1713
When I think cowcatcher I think of those long slanted pilots like the old wild western 4-4-0’s have. I really can’t call many diesel pilots a “cowcatcher” although I have seen photos of some steam locomotive styled pilots having been installed on diesels such as: https://www.flickr.com/photos/mjscanlonphotography/38407581694 I would definetely call that pilot a ‘cowcatcher’ because of its slated design.
Most modern diesel’s in the USA have snowplows for a pilot. This is sort of to give them an all weather purpose use; when you have such massive systems as UP or BNSF a diesel might be running the Sunset Route or Southern Transcon one day; then charging through snow on Donner Pass the next. Versatility and adaptability has made it so that snowplows are the defacto pilot for most modern engines.
However, before the modern era of mega railroads, a lot of lines had more specialized pilots. Southern or warm weather lines might just be a flat piece of cast metal, since there was no chance their locomotive would ever travel through snow. Other lines had special snow pilots that shops added before snow started… Western Pacific for example had some really cool snow plows they installed on engines in their Stockton shops for the winter, released on the system for the snowy season, and then removed again for summer: https://donstrack.smugmug.com/UtahRails/Dave-England-Photos/Western-Pacific/i-XXmbXXX/A

Okay. So if they’re of no real use then why were they built so sturdy?..
they have a real world use , the snow plow type can remove a modest amount of snow off tracks , the others can remove obstruction off track that might caues a derailmemt if it got under the locomotive , like tree limbs , cars and the likes.
This one looks like it’s ready for Donner!

They also act as protection for the traction motors, so I’m told, if obsticals like tre brances were to fall on the track, the plow would push them aside, not long ago, there was a thread of where a CN trains hits a few trees, maybe less than a month, but I can’t seem to find it anywhere!

check out this snowplow pilot.

One of the differences is era or time period. What was often referred to as a cow catcher is the pointed assembly on the bottom front of older era steam engines, usually with bars mounted parallel and meeting at a point.
A snow plow is simply that, a snow plow which various railroads mounted on the front of typically a diesel engine. Some steam engines had snow plows mounted - such as some of the narrow guage steam engines in the Colorado rockies.
Visually snow plows a fabricated usually from sheet metal but a cow catcher is comprised of parallel bars of usually metal.
Throwing around many different terms that overlap and that apply to different engines.
The steam engines have a pilot. Really early engines that had to contend with open ranges and un-fenced land had a large pilot meant to deflect animals or other objects from the tracks. That’s a “cow-catcher”.
It didn’t really “catch” cows, it deflected them. There were "pilots that caught things, they were mostly used by trolley lines and were designed to catch people. It was a hinged screen rectanguler screen in front of the trolley. When they hit a person the person would fall toward the trolley and into the screen, which would rotate horizontal with the person on top, “catching them”.
As engines got larger, the need to deflect things with a big long pilot became less, they weighed so much they could just push stuff out of the way. The pilots became shorter. The intent was a the same, to prevent objects from reaching the wheels of the engine. They just didn’t need a 10 ft long thing to do it. There are Federal regulations that require a pliot and set minimum standards for how cfar above the rails it can be. It has no bearing on the shape or styling, just that it has to be there and how of a gap there can be above the rail.
Engines that did switching needs someplace for the brakemen/switchmen to stand and ride on the engines while switching and moving. So “foot boards” were added as places for them to ride. Switch engines operated at slow speeds and rarely on the main track so they tended to have flatter pilots with a footboard all the way across the front.
Diesel engines, switchers and road switchers, have a “pilot sheet”, a flat metal plate across the front of the engine that does exactly the same as the cow catcher as the pilot, it deflects stuff and tries to prevent it from going under the wheels of the engines (trees
Probably for use on the line from Pocatello to Butte, maybe the Yellowstone branch if it was still in service at the time the photo was taken; or the wild wind drifts of Wyoming. The UP really wouldn’t have been running on Donner Pass before 1996; unless it was run through power on the joint City of San Francisco train the SP & UP ran together.

The term “Cow Catcher” to me always sounded like it should be a net or funnel that actually trapped the cows.
.
I’ll bet that even at moderate speeds that large sturdy triangular pilot would not really deflect a heavy cow, probably “cow obliterator” wouild be a better term but would not sound as good in children’s books.
.
Anyway, these pilots are like bumpers or I.C.C. bars on heavy trucks, they are there to protect the machinery that is vulnerable to road debris, or prevent anything from getting under the vehicle.

If the so called cow catchers deflected the cow out of the path of the train, that is a lot less obliteration than what I read about in Alaska. The geeps that traveled in winter would literally run mooses over and by the time the caboose cleared the scene, there was a lot of carnage between the rails.
The moose tended to prefer walking the tracks when the snow was deep since they were plowed regularly by the trains. The problem of hitting and running over moose was so bad at times the carcass would derail freight cars. The engineers would often get out on the front porch of the diesel when they came upon a moose and reach down with their snow shovel to try to “steer” the moose off the tracks. AFAIK, Alaska RR never added any kind of moose catcher onto their diesesl, at least not as of the Article I read in Pacific Rail News magazine around 25+ years ago.
I was watching a video about the Rio Grande narrow gauge division, they were traveling through a cow pasture and a few bovines were on the tracks, the engineer tried whistling to scare them off, all but one did, the one remaining almost outran the train till its legs got caught by the ties and the plow grabbed him, the vultures had hamburger by the end of it.
Important to remember that “cow catcher” is a colorful 19th century slang term for the locomotive’s pilot. AFAIK it was never used officially by anyone in the industry, nor was the pilot actually specifically designed to catch cows. The pilot was there to clear any moderate-sized debris off the tracks.
Considering all the grazing pasture that early railroads traveled through, I would guess cows were among the debris needing to be cleared off the tracks so the slang probably did not come out of thin air. There is a lot of colorful terminology from the “olden days”.
I know for a fact that cows will not get out of your way.

I was working at “7Ls” ranch one day and there were a bunch of cattle on the road and they refused to get off. I nudged them with the truck, blew the horn, revved the engine, nothing. The just stood there. I sure could have used a wedge shaped pilot that day!

I have seen some pretty old movies on You-Tube and elsewhere of cowcatchers in action. The locomotive always slowed down to a crawl when approaching cattle and other beasts of fine dinners, this allowed the infringing animal to be gently pushed to the side by the engine. A smaller 4-4-0 could be derailed by hitting a large beast at speed so unless caught by surprise, the crew would slow if possible.
This video clearly shows early hazards faced by the RR crews of the day.[swg]

Just my thoughts [:D][:-^]
P.S. A slow speed of course. I like cows. [;)]
