Advanced:
The route is locked when the approach section(s) turns from vacant to occupied. <br/>If the DelayedLock timer is not given (or zero), the lock applies immediately.<br/><br/>The route approach lock can apply to:<br/><ul>
<li>an entry signal: the proceed aspect of the entry signal is locked.</li><li>a (set of) route(s): in this case the triggering mechanism depends on the kind of route, e.g. entry speed.</li><li>a route body, in case the aspect of the entry signal or the properties of the route are irrelevant.</li></ul><p/>

Duration
Class   		Name: hasDelayedRelease
  		Name:  
 
Details:
Delay between the route cancellation request and the release of the route. <br/>The delay ensures that the route remains locked until it is certain that the approaching train has stopped or can stop short of the entry signal.<br/>This class does not specify whether release is automatic or manual. This is derived amongst others from the type of signal to which the locking applies.<br/>
Duration
Class   		Name: hasDelayedLock
  		Name:  
 
Details:
Delay between the moment the approach section turns from vacant to occupied and the moment the interlocking locks the route.<br/>
Length
Class   		Name: hasDesignDistance
  		Name:  
 
Details:
The distance in approach to the signal that is required for the approach locking. Typically the designer will select the TDS sections that are within this distance. <br/>
