Paper Crossings

The WTT entries for the Hutt Industrial Line contain examples of what are termed "paper" crossings.




"Paper" Crossings

The following paragraphs were sent to me on a mailing list.

All trains entering a Single Line Automatic Signalling area not controlled by Centralised Traffic Control system, or an Open Section must, must be scheduled to cross the last train off such a section at the border station irrespective of the time lapse within the same 24 hours or within three hours of the last train off such a section if midnight intervenes.

There are two types of train crossings - commonly referred to in train running parlance as "physical" crossings and "paper" crossings.

PAPER crossings are, in effect, technical crossings which are inserted to indicate to station staff and train crews that the arrival of one train governs the departure of another or conversely the departure of a train is governed by the arrival of another train. As the name suggests such crossings are shown on paper but the trains do not necessarily physically pass one another when running to time. During disrupted or late running, however, the paper crossing provides a safeguard because it is incumbent on station staff and train crews to ensure that all crossings are fulfilled or altered by appropriate instructions.



1947 Working Timetable

Referring to the page from the 1937 WTT which follows note that train 1741 crosses train 1748. The converse applies - Train 1748 crosses number 1741. The problem is that 1741 runs in the morning and 1748 in the afternoon.

In the 1947 WTT 1748 is shown crossing 1741 but 1741 terminates at Woburn (instead of continuing to Wellington) and no crossings are shown.

1740 does not "cross" 1749 because paper crossings do not extend from one day to the next.

In 1937 Staff and Ticket working was confined to special trains to Hutt Park. Other trains were worked under Open Section rules. The phantom crossings were probably part of the Open Section procedures.
