scope:

This Network Rail standard specifies requirements and guidance on the Hy-drive Supplementary Point Drive System which is used in conjunction with an In-bearer Clamp lock to create the Hy-drive Points System. This applies to systems that are used to operate NR60 Rail from C switch to H switch length.

This standard specifies installation information and set-up advice as well as key differences between the MkI and MkII designs. This standard applies to staff that are deemed competent to install and maintain the Hy-Drive Points system.

Purpose

The contents of this standard provide information on how to install and set-up Hy- Drive Supplementary Point Drive System when used on Network Rail controlled Infrastructure.

This standard will produce the relevant guidance and mandatory information to supports the installation and maintenance of the Hy-Drive Supplementary Point Drive System. Information published within NR/SIN/118 to mitigate the risk of flange contact with the Break-Out Device is contained within this document.

The Hy-drive Supplementary Point Drive System now has two designs known as MkI and MkII. This Work Instruction explains the key changes that were introduced in 2014 as part of the MkII design.
