Can class 745s call at Harlow Mill?

[Watershed]

I recently asked a member of station staff to arrange a Special Stop Order (SSO) at Harlow Mill, on a train operated by a class 745. This was due to a previous train being cancelled and it being a long time until the next connection.

The member of staff came back after a few minutes and said they were unable to arrange the SSO, because the class 745 would not fit in the platform.

Whilst this is of course the case (Harlow Mill is only 168m long whereas the class 745s are 237m long), surely the class 745s must have Selective Door Operation (SDO)? I know that the 755s definitely have it, e.g. to allow a single door to be released at Berney Arms.

If class 745s lack SDO, this would seem a huge omission.

If they do have SDO, is there some limitation whereby stations have to be in the calling pattern/original schedule for SDO to work correctly? And therefore it is not possible to add a SSO for stations where SDO is required?

Or was the member of staff perhaps just misinformed (to be charitable)?

Thanks.

(@dk1 perhaps you know the answer to this?)

 

[Class 170101]

It will be a station specific issue. Class 745s have only recently started calling at Waltham Cross as far as I can tell.

Depends on whether Harlow Mill is in the ASDO system. The risk would not be put on the driver to manually override unless it was an emergency.

Even then it depends if the specific station is risk assessed and compatibility checks are done - for example, 195s were not permitted to call at Ravensthorpe (even though it was an option in the ASDO system) for quite a while after they were introduced as the required checks hadn't been completed. It's possible that the same is true for 745s at stations they're never booked to call at.

Ok, thanks. It seems rather an omission if Harlow Mill isn't in the SDO database, after all it's a perfectly plausible location a train might be held in the event of disruption.

No, 745s cannot call at Harlow Mill nor any of the other 8 car length platforms between Liverpool Street & Cambridge/Stansted with the exception of Seven Sisters, White Hart Lane, Northumberland Park, and (most recently) Waltham Cross.

If there was severe disruption or say it had failed & the train terminated that would be different. A SSO is a known about problem so would not be classed in the same way.

I see. It still seems wrong to me - it means that during engineering works, as over the recent Bank Holiday, 720s have to be used for any train that calls at these stations. I'm surprised that 745s haven't been cleared since they were introduced.

Same with stations Brentwood to Maryland inclusive along with Needham Market on the GEML. The 745s just wouldn't release doors at any of those stations except in an emergency.
