Creep Adjuster

A creep adjuster is normally used when extensive work is involved. The creep adjuster is set at the centre of the length of the track, to be tackled, with the wide joints behind it and the jammed joints ahead of it. The following steps are adopted.

1. Expansion liners of the correct size are put in all the expansion gaps.

2. All the keys on this side of the creep adjuster are removed and all fish bolts loosened.

3. The creep adjuster is then used to close up the gaps to the required extent by pushing the rails forward. A gap of a few inches is left behind between the rail ends opposite the adjuster.

4. The corrected rails are then fastened with keys. After that, the rails on the other side of the adjuster are tackled.

5. The operation leaves some of the expansion gaps too wide which are tackled by the creep adjuster when it is set in the next position.

6. The corrected rails are then fastened and the adjuster is shifted to the new position.

7. The whole process is repeated again and again till the requisite attention has been paid to the entire length of the rail. In the end it may be necessary to use a rail with the correct size of closure (bigger or smaller) to complete the work.
