  3. Blocking Procedures Applying the Rules Hand Operation for Dual Control Switches 5/23/2012 3_01_a When dual control switches in a control point do not indicate to be lined and locked, movement must be authorized past the Stop indication. The employee must be instructed to operate the dual control switches by hand. First, remember to: • Apply blocking to all switches at the location to ensure switch control requests are not initiated. • Apply blocking on any track segment that can be accessed through the out of correspondence switch. • If opposing signals at adjacent control points in either direction indicate to proceed on any track that can be accessed through the out of correspondence switch, arrange to place those signals in Stop position and apply blocking, or, advise the opposing train of movement to be made and wait until opposing train has taken the opposing signal before authorizing movement and instructing hand operation of the out of correspondence switch. Accessed by selecting corresponding button. Begin with image. Then fade out to present bullets. “Apply blocking to all switches at the location” “Apply blocking on any track segment that can be accessed through the out of correspondence switch” “Arrange to place those signals in Stop position and apply blocking, or, advise the opposing train of movement to be made” Image/diagram representing a dual control switch that is not lined or locked. 3_01 Out of Correspondence Switches Hand Operation of Dual Control Switches Train Entering Track within CTC or Manual Interlocking

  4. Blocking Procedures Applying the Rules Hand Operation for Dual Control Switches 5/23/2012 3_01_b A train or engine’s authorized limits will extend to adjacent control points in alldirections on all connected tracks when granted permission to operate a dual control switch by hand at a control point or manual interlocking unless specifically instructed otherwise. Do the following before granting permission to operate a dual control switch by hand: • Apply blocking to all dual control switches that are accessible by the train or engine in the limits described above. • Apply a track block to the affected tracks. Note: Do not grant a train crew permission to operate a dual control switch by hand that allows access to a track where Track and Time is in effect without first giving the train Track and Time on that track also. (see additional narration in screen area) Accessed by selecting corresponding button. Begin with image. Then fade out to present bullets. Present bullets one at a time. Image/diagram representing a dual control switch operated by hand 3_01 Out of Correspondence Switches Hand Operation of Dual Control Switches Train Entering Track within CTC or Manual Interlocking Grant permission as follows: (Train) at (location) has permission to operate (specific dual control switch(es)) by hand (for switching moves only, to double train together, etc.- OPTIONAL). Establish conflicting routes and authorize conflicting movements only as follows: • Communicate with train or engine crew first given permission to place the dual control switch in hand operation. • Issue track and time to both trains. • Issue track and time first to the train that has the switch in hand operation.

  5. Blocking Procedures Applying the Rules Hand Operation for Dual Control Switches 5/23/2012 3_01_c Except as provided in Rule 44.21, when a train is authorized to enter a track within CTC territory or Manual Interlocking limits, verify that there are no conflicting movements before granting authority. Do not grant authority contingent upon a condition. Protect the movement by applying track block(s) to the affected limits. The blocks must not be removed until the movement has entered the track and is protected by block signals. Accessed by selecting corresponding button. Begin with image.

  19. Blocking Procedures Applying the Rules Scenario Exercise 5/23/2012 3_06 Now that you have reviewed some of the rules governing blocking requirements and processes, let’s check how well you can implement them. You will be presented with scenarios dealing with Hand Operation for Dual Control Switches, main track authorization, parked equipment on the main track, change of direction, and single locomotive movements. Each of the five images is a button that will lead the learner to a scenario. The learner can scan through the images using the left and right arrow. Once the learner enters the scenario screen, they will be prompted with a situation concerning protection of one of the five issues mentioned, and instructions. They will make decisions based on this information and the established procedures from the lesson. The learner will have an opportunity to recover if the situation permits. 5 images, each representing a scenario Intra-screen navigation arrows 3_06_a 3_06_b 3_06_c 3_06_d Title of Scenario-Based Activity
