How difficult/repetative is module 2?

[Jerry1237]

The use of lineside signals versus a layout without isn't really the point of the module. M2 is there to show the examinee understands the principals of signalling design and can apply them to a layout. The signals are just the end result for signalling principal application.

A usual level of understanding would be IST (or local equivalent). Ask more if what I've tried to explain doesn't make sense.
