Selective Door Opening in the future?

[455driver]

Is that just down to the driver not selecting something on the TMS to inform it that x number of coaches have been uncoupled and the train is now only y coaches long?

No, strange as it might seem, not everything is the drivers fault! :roll:

Southern's SDO system (on the 377s) can select to individual carriage level, not just 4 or 8. That's why they have all those irritating announcements about which individual carriage number you are in, even when 8 of them were dropped off half an hour back...

New PIS updates have removed that. It now only plays when the train is too long for the platform.

Brilliant, a needed adjustment.

Hope they had something left in the budget to program in 'Southampton' Airport Parkway', aka the station with no name...

Yes, pressing UNCOUPLE tells that unit it is no longer attached to another unit and the TMS reconfigures itself accordingly. COUPLE doing the reverse.

377s are already pretty clever a 4 car already opens the front 3 coaches at Pevensey Bay in the down direction and rear 3 in the up so not to block the crossing

That seems unusual though - every short platform I've ever used only releases the front 'n' and if the crossing is blocked (Billingshurst, Littlehaven, for example), too bad.

I've seen it done with non-SDO stock - EC 9+2 HSTs will have either/or/both front and back carriages off the platform depending on the station.

I think its because its selective door opening within 1 unit wheras most of the other Southern 377s SDO is within multiple units. EG Opening 7 car s doors at Christ Hospital.

Should have emphasised that I meant 377s, with their auto-SDO, as releasing doors only on the front n coaches.

Is there yet an industry standard method yet that could be installed on all platforms and units?

 

[Domh245]

Like the industry standard coupler, industry standard seat, light fitting etc? Unfortunately, until we have a coordinated rolling stock industry, we shall continue to end up with a diverse range of things that don't get on with each other, unless the DfT or the TOC specifically request compatability. For example if you mandated all Multiple units use a bombardier made SDO system, then the cost of the bids from other manufacturers would be increased, or even withdrawn in extreme circumstances.

On the subject of commonality, it is happening anyway surely? SWT have had a common ASDO system fitted to Siemens 444/450 and Alstom 458/5s, it's the Tracklink III manufactured by Hima Sella.

Tracklink III is a development of their Tracklink II SDO system used on SN's Electrostars. Seems they also do the SDO and CSDE for LU - maybe there is becoming a standard fit after all?

As all trains become ETCS compatible, using the ETCS componentry (ie balises and the positioning data available) will standardise it. Class 700s will be doing this for CSDE - Correct side door enable in the core.
