How does weather effect trains? Does fog and rain slow them? What about snow? I there is a tornado warning for the county that a train is in, will the dispatcher warn the engineer and conductor? How does snow effect trains and even duststorms? You can see I want to know it all. I hope I’m not asking too much at once![:D] In basic, just how does weather effect trains? That’s basically what I’m asking.
In general, your everyday weather will not effect train movement. I was running south one night and we went thruogh a snow storm so bad that the snow was piled up on the front of the engine we had to go out the back just to clean the front door out. I slowed the train down to 20 MPH just so i could see the mileposts and the whistleposts. We do have a system in place that we will be warned if a severe weather warning does come about.
Willie2,
So long as the rail is above water, and we can see, somewhat, where we are going, we go!
About the only thing that would stop us is when the rail is 4 inches or more under water, or hail, snow or rain that prevents you from seeing far enought down the tracks to proceed safely.
And if you do have to stop, you better tell the dispatcher, and get his or her permission to do so. They will most likley let you limp into a sideing, but you never know!
Stay Frosty,
Ed
You know that is an intresting Question. I personally have never seen submerged rails. I have been through the densest (sp?) fog, and I went about 10MPH less then the posted limit. (or I advised the engineer too) and we both had our nose pressed to the glass looking at the signals… Odd enough, One of the signals (Double Restrictive) was Gren/red But the red wqs much brighter then the Green so we immediately put the breakes on and almost came to a hault before we could see the green one.
thats the worst i’ve ever been through
It’s probobly not much compared to other people
OH yeah and another thing, one time we had about 15 inches of snow, and we just plowed right through it!
really didn’t hinder us mush, we wereonly a minute and 30 secondes late at the end station.

stopping to switch in a yard on a cold cold cold day can be very frustrating for a crew.if the cars have been in the yard for awhile it takes time to get the air up(brakes).
stay warm
stay safe

The reason I asked this is because in Omaha tonight we have hail, downpours, lightning, and yes, even tornadoes! Whacky weather! This made me think, “What do trains do in this kind of weather?” Thanks for the answers!
Sounds like you train guys have some explaining to do! This is a topic of interest to me…
It’s a lot easier to move when the closest thing to a steering wheel you have is the switch rod!
Btw, red is naturally more bright than green. It seems darker, but that’s just how it’s percieved. I suppose I should say red is stronger than green.
When it gets too cold outside (like 10 below), isn’t there a special restricted speed limit? If there is, what’s the reason?
Thanks.[:)]
…History tells us that trains [Passenger], did run through the roughest of winter snows and cold, [and I remember they did], etc…but I’m now wondering if that is really not the case anymore. Example, recently the bad weather over Labor Day seemed to stop many of the trains on the east coast. Some simply canceled. I wonder if the railroads now operate with so much less support crews to handle emergencys that the powers to be simply can’t keep the schedules and in some cases cancel scheduled trains. Does possible insurance claims possibly now enter into the equation.
One thing the UP is subject to, more than some roads is high winds. All trains have “blow over” wind speed based on the car type and when the winds exceed that speed, they stop trains until the wind gusts subside.
Tornaodoes the train stops and the crew seeks shelter in the nose of the engine.
The two worst weather calamities are heavy rains and ice storms. Heavy rains means possible flash floods. Ice storms means downed trees, power lines and signal lines.

As for speed restrictions in cold weather, rail gets brittle at cold temperatures. It also contracts. There are also restrictions in hot weather, sun kinks, where the welded rail expands and the force rips it right off the ties.
Most railroads use commercial power to run signal systems and whatnot. When the power goes out, so do the signals.
And, of course, the threat of lawsuits might stop more trains than anything.
I just remembered another one which is if its 10 degrees below zero or colder we are limited to a maximum of 75 car train length due to the fact of the amount of time it takes to charge the air on the train. kinda good to have when you need your brakes.
oh I forgot too if you get enough snow ice and cold if you have a bad switch heater a switch could be frozen open or shut Yikes![:0]
stay safe

the only restriction in bad weather is the engineer. if i want to slow down i will mostly i run track speed. its been so foggy around here and the engine i was running didnt have a ditch light switch to turn it off i will run with out ditch lights it helps me see with out them. the only problem i have in foggy weather is cars running into the side of me. in snow i just apply the brakes early so to melt the ice build up on the shoes. in storms those engines go right thru trees. and i have never damaged a engine. the dispatcher will let you know about tornados and such but you keep rolling . this is a good way to see who knows the territory is if sight is limited a good engineer will keep his train at track speed with out doing anything differant than normal.
wabash1-a few questions.
If you want to slow down, you will run at track speed? What speed do you normally run?
You turn out the ditch lights to see better? I thought the FRA mandated ditch loghts for any train that exceeded 10mph, and that crossed a road at grade?
You keep rolling during tornado warnings? Why?
Your definition of a “good engineer” sound a bit like a manager’s description. Are you working you way up to management?
Omaha Willie2:
The operating guys have added pieces of your question to the equation, let another add a few more:
(1) The railroad rules say you can’t run a locomotive on track with 4-6 inches of water above the track. The main reason for this is that the locomotive traction motors will suck water into the casing and ruin the windings for the electric traction motors over 4 inches above T/R (top of rail). The speed gets reduced to 5mph because you can’t see the rail or track below AND any faster and the traction motor blowers will splash or suck water up into the traction motors and short them out (bad news, no go, kaput!)
(2) in extreme heat / cold, you have pull aparts and or sun kinks with the rails. At speed the forces on the rail are at their worst, therefore we back off on the speed for fear of setting off a rail defect.
(3) Joe Koh hinted already at what a beast it is to keep trainline air cold weather and what kickers do to your day. Somebody else can do the hydraulics/physics lesson.
(4) I have worked 3 derailments caused by train crews running too fast for conditions. (A) In blizzard conditions, a train passed a red signal caused by snow jamming switch points open (gap in the points) at 40 instead of at restricted speed - the power and the first 20 cars got scattered on the station grounds, (B) a train in fog went too fast in fog through a diverging route (thought they were going straight) and the result was similar to the Chicago METRA derailment of a few weeks ago and (C) in a driving rain storm, a train slid past a red signal on wet icy rail and went through a power derail protecting a crossing frog in yard limits.
(5) I have hi-railed main track during floods with water coming up above the running board/ bottom of truck door. You learn to repack bearings in the high rail gear and relubricate immediately afterwards. Railcar axles/journal assemblies get inspected if they have been submerged for the same reason. Highrail truc
Back in the late 40’s out here on the Canadian Praries there were really bad snowstorms and one train got stuck in the snow so bad that they had to just leave it in there until spring. I remember seeing in a book of mine a picture of an Australian steam engine partly submerged in water and actually running. I remember it saying that that type of engine ran very good in floodwater.
When your running in bad snow… and alot of snow blowing up as the train goes,… i make a brake application from time to time to melt any snow and ice that has packed itself around the brakes… that is even a rule in CSX train handleing rules. …
in bad rain…unless their is a flash flood warning out ( a form W on CSX), we just keep on trucking at tracks speed. with a Form W,.we have to approch all bridges and colverts at restricted speed… now amcrash on the other hand…with a Form W…they have to do restricted speed from the start of the Form W…to the end of the Form W limets…and the limets are posted in your Train Bullitens…
as far as strong winds…you just keep going…and hope thier isnt any trees down…becouse thier is no way to know, unless it takes out the signal system…and then its restricted speed from the first “bad” signal to the next signal that we get that is more favorable then restricting… haveing done this on more then once…it makes for a long day or night… nothing worse then haveing to go looking out 1/2 the rang of vistion for mile after mile!!!
fog…welll that stuff just sucks…i just keep going track speed and if i see yellow…i start to slow down NOW!! but even with the thickest fog i have ever seen around where im at…you still can mananage to see some land marks close to the track… knowing your territory and land marks is a big help when your running “blind” lol
csx engineer
CSX engineer hits it right on the head. The only thing is here in good old CONRAIL country form W’s are not for our use. We will just get an attachment with our dispatchers bulletin or a line 13 on our form D’s. He has a very good point that you have to know your territory like the back of your hand or it’s a good way to take a bite of a s**t sandwhich. Besides if you slow down because of bad weather its easier to stop for coffee and get away with it.
Have we heard from Ed about any effect the Houston weather had on him?
