Track bash Barking sidings

Interesting! How many shunt signals does that move involve, 5?

4 I would have thought!

1 from the w/b platform wrong road
1 at the inlet
1 at the end of the road passed through (21 - 25 only)
1 at the outlet.

aspect is correct - 4 shunts

This is possible thanks to rule changes made in September 2011, although there has been a sneaky change whereby it can be done relatively routinely now rather in special circumstances only when it first came about.

Rule book 5, section 12 covers it - all we need these days is the signallers authourity; no scotching and clipping required.

PLEASE NOTE:

The train service will now use the eastbound platform at Barking as planned tomorrow - the possession limits will be corrected overnight and thus you will no longer be able to bash the sidings.
