Hi,
Am trying to attempt 2009 paper and got struck at the Shunt Overlap. In the layout the overlap symbol is shown for few shunt routes and not shown for the other.
For example, route 418C(S) leading to 382 - overlap symbol is shown on the down branch line as 180. Does that symbol is applicable for this shunt route also or used purely for main moves like 416C(M).
Route from Independent ground PL(Shunt) to another Independent PL is provided with an overlap where as the route from GPL to main signal(i.e 418C(S) ) is not shown with the shunt overlap.
So, when the overlap can be considered for the shunt move and when can be omitted? Please clarify.
Thanks in advance.
Regards.
