Train felt like it was derailing

So how do we educate the public to act sensibly and how do we distinguish between offering good advice and bad ? Should we never say anything and stick to TOPS requests and seating configurations ?

We are very quick to put down any use of the passcom and hammer into people in those threads about using it sensibly. A potential derailment is valid. I've been passcom'd for some very stupid reasons. I would rather help educate people than constantly berate and castigate them. Just as I'd say in those threads where there is clear misuse. If you feel you are in danger. Pull it. I can count on one hand the number of times I have had a genuine passom. They frustrate me but that is my job to deal with it.

There is a whole thread about Lewisham and people egressing onto the track. There are many threads about people who will pull a passcom because they were overcarried. This is probably the first time I have seen someone report a genuine concern over train safety.

My 'encouragement' is for people to act when they have a safety concern or belief they are in danger. I think that should be supported.

100% with you on that.

The lurch to the right at Cogload Junction heading in the up direction between Taunton and Castle Cary can be quite disconcerting.

I've learnt not to be pouring my wine, or putting food to mouth when on the Pullman services. Staff tend not to silver serve at this point either!

Coming the other way on the down Berks & Hants, there is a very noticeable bump and lurch at Hampstead Marshall LC. This one is a real filling rattler. It's been reported numerous times by staff and passengers over the last 18 months or so, but is still there.

I think it's exacerbated on 143's due to the shorter wheelbase.
141s, which were even shorter, used to vibrate a fair bit at speed on the rare occasions they got any. Between Deighton and Mirfield was particularly bad.

As we're now talking about general rough spots, here's one that falls into the category of "rough, but fine/safe": going through Mirfield (again) on fast services towards Huddersfield there's a couple of sharp jerks in close succession as the train passes platform 2. Looking at the track from the platform you'd never think of it as sharply curved, so it is surprising. You can always tell the uninitiated travellers as you pass there, they're the ones who don't make sure they're holding on if standing!

Back in 2004 I was on a FGW HST from Paddington to Penzance. We'd were up to speed out of Paddington when I went to the buffet car for some food and, as I was being served, there was a violent lurch one way. I was almost knocked off my feet - I had to brace myself against the inside of the carriage behind me - and the lady serving me looked very surprised. I guess it must have been somewhat out of the ordinary for a member of crew to look surprised as I guess they must experience everything and know what's normal and what isn't.

I’d urge anybody to alert staff in this sort of instance. Never assume the crew have also felt the same ‘judder/jolt/jerk etc. It often depends on which part of the train you’re positioned as to whether you fee certain movements as well I guess? Just general physics, but I’m no expert.

True, the ride is usually rougher over the bogies than centre carriage for instance.

I suppose it depends on the length of the train, but I’d imagine it’s ‘bumpier’ in coach 12 of a 12 coach train too?

I would say that unless it's a tilting train it wouldn't be any 'bumpier' coach to coach except for natural wear and tear being different coach to coach. Coach 5 might be the roughest on one 12-car but it might be Coach 11 on another?

Why would you say that the last coach would be bumpier? Just curious, there may be something I've failed to consider.

I’m just thinking about how things move about to be honest partly from a mechanical aspect. For example, I just thought the back end, being the tail end so to speak, would be less well ‘planted’ to the track? If you compare that to say, the middle of the train, where there are carriages either side? Not sure I’m making sense but it’s just my train of thought....excuse the pun :)

Not at all, I can understand your thinking and it may well be right. I would imagine that the air passing over the train (the splitstream) could create a bit of instability at the rear but it may not necessarily noticeable I've no idea.

Elasticity can cause a bit more movement at the rear compared to the front, because of the forces transmitted progressively from car to car via the couplers.

Back Cab
[QUOTE="LowLevel, post: 3950242, ]

I've been involved in several incidents on trains and for the most part the passengers just ignored what was quite blatantly something very wrong.

[/quote]

On a late evening train a coal train passed me shedding its load on one wagon. Sat in back cab I heard a horrendous din as its load clattered and smashed against the side of my train. when I walked through the train I found 4 outer skins smashed. Two of them next to punters who didnt even pay any attention or say anything about the obviously smashed window next to them. Even my driver hadn't reacted to the shedding load!

I often used to notice, back in the day ;) (early 1980s) must have been Mk3 I guess on the New Street - Euston services, that when up to speed around Marston Green before braking for International, the rear coach would vibrate left/right really quite violently. It used to make a right racket. I don't know if it is the same as already mentioned in this thread.
Maybe it was due to the fact that it had nothing behind it to keep it steady. I did tell someone at International once.
I never heard of a derailment along there so I suppose it was all normal.
