Q: If an electric train is heading east on a westbound track and the wind is out of the north, which way does the smoke blow?
A: they don't bury the survivors!!

What happened to the missing dollar?
$2 + $25 = $27, as the men paid a total of $27 with $25 going to the hotel and $2 to the bellboy.

zardoz Two trains travel toward each other, beginning 100 miles apart. One train travels at 40 miles per hour; the other travels at 60 miles an hour. A bird starts flight at the same location as the faster train, flying at a speed of 90 miles per hour. When it reaches the slower train, it turns around, flying the other direction at the same speed. When it reaches the faster train again, it turns around -- and so on. When the trains meet, how far will the bird have flown? (Discount any factors relating to friction, either air or ground)

The combined speeds of the trains is 100mph. They will meet in one hour. In the meantime the bird has flown 90 miles; it doesn't really matter if he is flying between the trains or took off for Kalamazoo.
Any bird flying 90 miles per hour isn't going to last an hour. It will fall to earth long before the trains meet.

zardoz Firelock76 zugmann Firelock76 By the way, if anyone else comes up with one of those cockamamie math word problems that drove us all nuts in school there's gonna be a complaint to the moderators! A boy slides a block of ice on an inclined plane of 13 degrees. Assuming no friction... OK, who's the @#$% moderator on this site? Think I was kidding? Three men were on a business trip and had to stay in a hotel over night. The price of the room was $30.00, so the men decided to split one room, three ways. Each one paid $10.00. Well, after they paid, the manager realized that he overcharged them on their room. The room only cost $25.00, so he gave the bellboy five one dollar bills to give to the three men. On his way up to the room the bell boy was trying to think of a way to split $5.00 three ways. After thinking about it awhile, he decided to keep $2.00 for himself and give each man $1.00 back. Now, if each man (who paid $10.00) gets $1.00 back that means they each paid $9.00 ($10.00 – $1.00 = $9 ). $9.00 multiplied by three (because there are three men) equals $27.00 plus the $2.00 the bell boy kept equals $29.00! What happened to the missing dollar?

Well... later 2 men came and that same manager charged them $20.00 for a room and each paid $10.00 and likewise, he later realized that he had overcharged them by $5.00, so he called the bell boy over and gave him 5 $1 bills to give back to the men. On his way to the room he again realized that he would have a problem splitting the extra $1 if he gave each of them $2 back... then he decided that since he was having to go to the third floor to deliver the cash and that was an extra flight of stairs it was worth an additional "tip". so he stuffed another $2 in his pocket and paid each man back just $1.00
So, each man paid $9.00, which multiplied by 2 equals $18.00 plus the $3 the bell boy kept is $21.00
That is where the other dollar went!

Therefore 9/9=1=.999999~
.999999~=1
Or more simply:
Let 1/9=.1111111~Then multiply both sides by 9;(1/9*9=1)=(.111111*9=.999999~)
Result: 1=.9999999~

It's the summer of 1980. A quartet of nearly new GP40-2s arrive Beacon Park from Selkirk with a van train. The engineer reports having the ground relay trip a few times on the trip. Did not seem to be related to how hard the train was pulling, whether or not the track was smooth - just random. Once push of the reset would keep things going for a couple hours. The weather is cool and dry and has been for the whole trip.
The shop found and solved the problem in a few minutes. An apparent rule violation was involved.
What was the cause of the ground relay trouble?
Did it have something to do with the dynamic brakes?

Thanks to Chris / CopCarSS for my avatar.
Applies in both cases!
A randomly created intermittent pathway to ground, which trips the GR and then disconnects; before a GR reset, the stage then is set for the next sporadic creation of the electrical route to ground......lot's, a huge, amount of a possible cause....until "may involve a rules violation"
"the shop quickly found....." Thus, there was a fueling track electrician that didn't find the cause, but in the shop the cause was "quickly found." "rules violation?".......were they mechanical department rules? Operating rules don't supply answers....easy ones, anyway..... One, maybe a trio, of additional facts (hints), not only facts , will permit solution....
Sherlock, I imagine kinship....

They made the whole trip from Selkirk to Beacon Park by hitting the GR reset a few times. Shop and fuel pad at Beacon Park are (were) really the same thing...
Operating rule is one EVERYONE knows... even railfans. And was not so rigorously enforced until recent times.
Expect a train on any track at any time?
I like my first one better.

(g) sounds like a beer can in the electrical cabinet or a firearm.
Call was why is a freight car off the track on the ROW ?
Do not know who made the call but one time on the SOU RR rat hole division a freight car in middle of train jumped out of the train and the rear somehow re coupled to the front of train. Conductor coupled up air hose and train continued on.

Yep!
I've heard the ground relay one in many places - but it involved a metal flashlight.
Also every line that has a grade has the story of the car that popped off the rail, while the rest of the consist couple back together.
I can believe the first one (I've seen many starting fuses rolling around in that cabinet), but the 2nd one? I remain skeptical.
Once had an old RRer tell me when you open up a hop-toad derail, to always re-attach the lock on it when in the open (non derailing) position. Once saved him from discipline. Any guesses why that would that be?*
*-probably a question for the non-RRers. Also is probably one of those legends that has traveled many miles on many railroads.
It's been fun. But it isn't much fun anymore. Signing off for now.
The opinions expressed here represent my own and not those of my employer, any other railroad, company, or person.t fun any
Cause the derails tend to re-apply them selves under the moving cars unless they are latched open.. been there , seen the wreck
And, I have watched as a car ran over a rabbit--and stayed on the rails. It was being moved from the AT&N to the GM&O (in Reform, Alabama). There was a man on it, trying to stop it before it reached the derail, but the hand brake did not work. As it was, the GM&O section foreman lived right by the interchange, and he came over and unlocked the derail so the car could be moved back to where it did not foul anything it should not. I do not recall how the car was held in place until the GM&O was able to pick it up.

Another story from Trains regarding undetected derailments had a car (or at least one truck) derailing and riding along the ties for a considerable distance before righting itself.
It probably would have gone largely undetected (at least until MOW saw the marks on the ties) were it not for a dispatcher trying to throw a switch.
Seems the errant truck hit an electrical box, causing that particular circuit to malfunction.

I think just about every railroad claims to have had this happen to them at one time.

zugmann [snipped - PDN] I've heard the ground relay one in many places - but it involved a metal flashlight. . . . I can believe the first one (I've seen many starting fuses rolling around in that cabinet), but the 2nd one? I remain skeptical.
. . .
Would the ground relay's current have been strong/ large enough to burn/ melt away the point(s) of contact with the thin aluminum beer can, thus breaking the 'ground' until the can rolled around again to a different point ? That could make it real difficult to find and/ or diagnose (unless at night - it might cause a flash . . . see article referenced above).
Depends on the locomotive model. The older ones took quite a bit more current than a new engine. I think the Sd40 tripped at .011 amps and 74 volts. I've seen taconite pellets in traction motors that cause the most frustrating ground relay issues you can imagine. Once the engine was in the shop the problems disappeared.
I got a funny story regarding that particular engine I'll tell someday.
I think it was a western line (SF or SP).
