Dear Sirs,

Is it possible that a complete route without an exit signal? It seems that the route of fixed signal 321 is a route without an exit signal.

A route always has an exit; almost always this is marked by something lineside denoting an end of movement authority and that is generally a signal, it could be a STOP Board or a buffer stop etc.  In the case of a shunt route it could just be into a fan of sidings / depot as the driver will have received an aspect permitting them to proceed cautiously "as far as the line is clear" using line of sight and regulating speed accordingly.

There are cases where lineside signalling (generally Track Circuit Block) reads into another form of signalling that requires a token and that token may be physical or perhaps it reads into some form of in-cab signalling and there is therefore a transition.  In general there would be some form of signage to mark the spot at which the set of operational rules changes and this may be "at" a signal, but perhaps could be at some intermediate place.

However I think the question to which you really want an answer is "what do I do for a route for which I have been asked to produce a Control Table but goes off the area depicted on the plan?" 
The answer to that one is make a suitable guess of what there would have to be, state it as an assumption- may be best to do a sketch to show (or even annotate the layout question paper and number it as one of your answer papers and hand in with them) and give it an exit signal and anything else you think may be needed such as a distant, one or more track circuits and possibly some control regarding the establishment of direction on a line that is used in both directions or any other reason why there may need to be an element of cooperation between "your" signalbox the plan of which you can see and the "other" signalbox that you'll need to imagine.
The question is a good one to see what you can infer from your experience and demonstrate your understanding, rather than just being able to follow a process

Thank you for your reply.

I tried to complete the control table, and attached.

Please feel free to provide comments/suggestions, as I would like to do more practice on control table.
