Steam Br Class 377/3 Add-on - Bug In The Sip On The Ghost Train

The "Southern BR Class 171 & BR Class 377/3" DLC includes a very interesting ghost train from Brighton to Newhaven Marine in the attached timetable.

This is quite a reckless idea, because we all know that after nine years of development and eight iterations, passengers in TSW6 still are unable to exit the train at the final stations. And this ghost train requires the entire train to be emptied of passengers at Newhaven Harbour station.

But what is even more disappointing is that the developers of this add-on forgot to include a destination called "Newhaven Harbour" in the PIS for their Class 377/3 train. Interestingly, the voice announcements work properly, and a nice synthetic lady informs passengers that the train is heading to Newhaven Harbour.

I know that this DLC is likely to receive a patch in which the Class 377/3 sounds will be replaced with those from the "Brighton Main Line: London Victoria - Brighton Route" add-on, so perhaps the developer could add the missing station to SIP in the process?
We will do our best to pretend that all passengers disembarked at Newhaven Harbour, and when changing cabs at Newhaven Marine, we will walk through the entire train with our eyes closed so as not to see passengers who have no right to be there.
Unless the developer breaks this service, as they cleverly (though not very elegantly) dealt with passengers at Nielston station in the "Cathcart Circle Line" add-on...

Thank you.
