SSP044 Iss 1

In certain circumstances reflectorised distant boards, as shown in Appendix A, maybe used in place of fixed distant signals. The boards should be positioned, where possible, on the left hand side of the line, at a height to the centre of the board of 2.5m above rail level, and as close to the running edge as structure gauge clearances permit. Although this document has been stamped superseded, it is not known by what.
