Reasonable HST emergency stop reason?

[heart-of-wessex]

Hello,

I am coming up with an idea for a RailWorks 2 activity where you can have the brakes slam on to emergency to a time set up by the author. I am thinking of using this idea for a realistic scenario, so either tripped by a passenger pulling the chord or something on the HST failing. I am looking at one whereby the HST can resume under whatever restriction if needed and to terminate at the nearest shack and run ECS to Old Oak. I am thinking of this triggering around the Hanwell area.

Would say a hot axle or 'funny smells from the wheelset' be enough to enforce a full stop then run at a restricted speed? Would a failed ATP or DSD fault bring the emergency brakes in?

I would like to make it as close to reality as I can, does anyone have any scenario ideas?


Regards,

James.

I was on an HST several years ago when an air pipe broke off between two of the carriages (or it might have been power car and carriage, can't quite remember) and brought on the emergency brakes. Driver effected a temporary repair of some sort to get us moved at walking pace as far as the next station (Leeds) which was thankfully close by but we were then de-trained as it wasn't deemed fit enough to carry on the full journey and presumably went off to Neville Hill for a proper repair.

An ATP fault would bring about a brake application (there would also be an F code displayed on the ATP speedo - such as F15). DSD failure would also dump the brakes but I'm not sure if the DSD can be isolated on an HST to enable it to move forwards from that cab at reduced speed.

Have a read through TW5 on rgsonline to see what failures would come with a speed restriction.

Broken window/outer skin, or a headlight failure would be two obvious ones. Also horn failure.

SPAD due to signalling fault is another option. ie. Signal fails safe to red when train is very close it causing a TPWS activation.

 

[Flamingo]

Or TPWS just kicks in for no apparent reason...

 

[driver9000]

Vigilance or AWS not cancelling.

 

[Adam_Harrison]

A train spotter sticking their head out the window and loosing it because they never seen the approaching train?

 

[Barrett M95]

Wrong-side signalling failure. EG - pass an AWS ramp with the signal at caution, but you get a "ping" instead.

Wont bring in the TPWS but the driver will probably stop (where convenient) and fill in the RT3185, no need for an emergency stop though although the driver will no doubt say a few words!

Obstruction on the line ahead eg broken down car on a level crossing if any on your route

If we get a wrong side indication on TVM it is emergency stop time. Not automatic - driver initiated. I assumed it would be same in UK!

 

[HSTEd]

Flashover in one of the traction motors? Or would that result in a failed train rather than isolating that motor and continuing at reduced speed/power?

A wrongside failure such as AWS code 5 or 7 must be reported immediately stopping specially if need be.

Thank you very much for the link to rgsonline, very useful! Never knew such existed until now. Some ideas cant be implemented like AWS fault or wrong signal aspects as RailWorks 2 will apply the signals correctly and i cant find a way to make it fail. i can trigger an emergency stop without the user doing it but i also want it where delays wouldnt be long, i dont think any train sim driver would want to sit there f
for 2 hours whilst a pretend ambulance comes along to clear up the remains of someone doing heads out but I know any incident would take a bit of time so id cut the time a bit then you would proceed to ealing BDY to detrain then run ECS to OO which would probably enter on the energency chord entrance road rather than run to padd to reverse the normal way?

So if you get a bell instead of a horn when approaching a cautionary signal, would you stop at the next station to report it or would you stop at the next available trackside phone and inform your control and signaller? I would imagine the later in case anything should happen on your way to the next station.

Personally I'd stop immediately and use NRN or any phone I could lay my hands on.

I think most people would. Very wise to do so even if it's not stipulated in the rulebook specifically

It is.

Anyway we digress from the subject....

If the OP is looking for an HST fault that would mean the train is a failure then assuming an ATP fitted power car (mentions of GW and Old Oak) then I suggest the following.

In the ATP display, the fault code F12 appears along with the alarm and a brake application. ATP failures cannot be recovered by the Driver so it needs to be isolated. As far as I know a train with ATP on an ATP line must then be withdrawn from service. I have no idea what the various F codes mean as I don't work on an ATP railway.

 

[es373]

Any fault with the 'safety critical' systems is enough to pull the train from service.
Bogie instability/hunting too.

For a new driver you seem to have forgotton some of the rule book. Wrong side failure is a stop immediately and inform signaller preferably in the signal section you are in when the error occurs. The wording "probably" and "convenient" in your post are not valid in this situation.

I would say in this scenario to keep it easy an AWS failure for instance AWS does not cancel, this will cause an EBA. The AWS needs to be isolated, maximum of 40mph with no competent person and OOS as soon as possible.

 

[Aictos]

Door left on catch after leaving a station could be one.

 

[es373]

TWPS brake demand on green aspect or within line speed.

Don't mention the war!
