South African Steam: 25NC 3407 to Cullinan - Epic Wheelslip starts a fire!

- A rare visit by a 25NC to Cullinan - 25NC 3407 hauls a wedding charter to Cullinan, and proceeds to get stuck on the turning triangle. Some serious wheelslip follows - the wedding ceremony apparently seriously interrupted by the volcanic eruptions just outside the church! Some of the guests even came outside to watch and take photos...
2.30: watching the flames lick in and out around the spinning wheel. INCREDIBLE!
Thanks! It was pretty spectacular!
THANKS a lot!
Cheers.
Don't they know that when a loco slips there are two things that should be in mind, either it is pulling too many carriages than it can pull on a step gradient, or the load is heavier than expected. It could also mean a brakes air hose or two could have disconnected on one of the cars (carriages). Slipping makes the situation worse because it wear out both wheels and tracks. If this locomotive had less carriages, would it still slip at this zone? Maybe not. Why? Because the load is lighter. That means, on this line the locomotive can only pull that many loaded carriages without slipping. In this videowe see it slipping but how did it happen. Has any slipping occurred in the past with this train at this area? If so, what has been done about the old boy? Continued slipping will destroy its drive wheels and if over loaded the locomotive boiler could explode.
It was on a little-used turning triangle, not actually hauling a load. It was on a sharply curved grade and the loco's wheels were a bit hollow. All good contributors to the slip, not to mention the mud created by the crew!
If they'd waited until a decent section of track had been gritted before attempting to start, they'd have probably got some lasting traction. The loco was OK on each shovel-full and them slipped to a halt on the next ungritted bit.
Yeah, there wasn't really a long term plan!
I guess that's a lot of damage to the tracks and to the locomotive wheels.
Yes not too much I think. But not really great though...
awesome video
Thanks!
4:45 Must be a NOVICE on the throttle. How difficult is it to "kill throttle" after wheels are slip, slip, slipping?
Haha yep, it was an experienced driver but I'm not sure why they let it slip like that...
In a British loco in related problems they had their hand on the cylinder release cocks which are much faster than the throttle. So when it started to slip they opened the cocks briefly permitting the wheels to grip then close the cocks. Repeat this as required.
Could be throttle lag or priming. How many steam locos have you operated, bud?
Slipping/skiding of steamer wheels maybe a problem .It is observed when engine gets started. This steam engine has set of 4 drive wheels. It may have maximum speed 120kmph.Thanks.
+Vishwajit Pawar I counted 8 drive wheels...
I have said a set of 4 drive wheels. 4×2=8. ie.s 8 drive wheels. Thanks.
I have never seen such a wheel slip .In India we have Baldwin USA on main broad gauge lines which are in service to till 1994 and TELCO with Yokohama Japan on metre gauge lines never witnessed such in India
Indeed, I would understand if it was a huge freight, so there must be something else at play here.
Yes it was crazy. On a steep leg of the turning triangle, overgrown worth grass. Loco wheels also were a bit hollow.
Very sad to see this loco today, or whats left of it at Worcester
Yes it was certainly a great loco in its day.
She’s slipping hard on the rails nice epic wheel slip fail
It certainly was! 😮
The poor old thing, at least they managed to get the loco out eventually.
Yes, I don't think it was meant to go down there!
Did anyone bother to check the handbrake's?
Yeah. The loco wheels were a bit hollow, plus a steep grade and sharp curve.
So what was the problem?
+Nickel plate road 765 a sharp downgrade and grass over the track made for a slippery combination! Add to that the dirt that was used for traction plus the water to put out the fire, and you have mud into the equation!
steamfreak3450 - Steam trains around the world OK now I understand
@@steamfreak Had the sanders failed???
Track sanders failed?????????????
Everything failed!
2:30=the fire in the wheel slip
Hot wheels!
How on earth did it catch fire?
The stones and sand under the wheels made sparks during wheelslip, setting fire to the dry grass...
I think there is something wrong with the regulator. It appears the driver has very little control.

The problem likely exists between the throttle and the engineers seat.
I wont say that steam engines are slippery sometimes, but that was purely the engineer being lazy or ignorant. Evidence given by the locomotives ability to start moving then spin as the pressure comes up in the steam chest from the (still) open throttle, you cant put dirt under a driver, it has to move onto the dirt/sand before it grips. There is a method of working the throttle so that you wont spin. It takes a moment from the time you open it before it hits the pistons, lag if you will. In this case you have to anticipate the lag. There is a lot of piping that has to be charged with steam when you open the throttle. Having a front end throttle reduces it but doesn't eliminate it.
Its like opening a valve on an air tank, just because you only opened it a little and its only putting out a little air, it will still rise up to the tank pressure given the opportunity. "Regulator" is a misnomer. It doesn't put out a set pressure. It opens an adjustable hole and does nothing to "regulate" the pressure coming out of it.
@@herpnderpn2484 My dad wad a driver on the LMS for 47 years throughout ww2. He, and other drivers used the drain cocks to help control slipping. Open the drain cocks and it changed the pressure characteristics in the cylinders.
Press your palms firmly together and rub vigorously. Feel the heat of friction? There's your answer.
0:26 how was the train moving with no side rods?
Hmmm, there must have been a diesel loco hidden in one of the coaches?
their are rods their....... pause the video and use the < and > keys to go forward and back one frame at a time
and its not like they took off the rods...... ran it a few miles.......
and then put the rods back on so he could get a wheel slip video.....
DisneyStoreFan1 They’re hard to see, they’re there. Otherwise the locomotive wouldn’t have a chuff to it.
Mantaf
Exactly
Scrap the relics 🚂🚃of past. go electric 🚋🚊locomotive. avoid global warming and🐒💭 pollution. 😭.fan
Bahahahaaa! Electric locomotives that are powered by coal power stations! 😂 Yep that will fix it! 🤣
@@steamfreak transformers power electric locomotive. Get ur facts right .🚋🚊
Wait! What? You mean like Optimus Prime? That's awesome! 🤣😂😅
