Select all that apply. 1. application & release test 2. an ETD (end of train device) 3. a DP locomotive 4. a gauge verified to be accurate - correct answer -A DP locomotive -A gauge verified to be accurate -ETD When conducting an inspection to determine if the brakes apply and release on the rear car, the brakes should apply with a brake pipe pressure decreases of ____ and release with brake pressure increase of ____. 1. 5 psi & 5 psi 2. 10 psi & 3 psi 3. 5 psi & 3 psi 4. 10 psi & 10 psi - correct answer 5 psi & 5 psi Dynamic braking and air brakes are being used to slow for a permanent speed restriction. The slack is bunched on a level grade and the engineer has just released the air brakes. The engineer should maintain enough dynamic braking to keep the slack bunched until _____. 1. air brakes release on the head and locomotive consist 2. air brakes release throughout the train 3. air brakes release on the first half of the train - correct answer Air brakes release throughout the train A crew is approaching a permanent speed restriction on a level grade with the slack bunched. The engineer will be using only air brakes to slow down. With the throttle in idle; the engineer will make a ______ at a sufficient distance from the speed restriction. 1. 15 psi brake pipe reduction 2. minimum brake pipe reduction 3. full service brake pipe reduction 4. 20 psi brake pipe reduction - correct answer Minimum brake pipe reduction When using throttle reduction to slow/control speed on an ascending grade, gradually reduce the throttle _______. 1. waiting a minimum of 10 seconds between each throttle notch reduction 2. as quickly as needed 3. one notch at a time - correct answer One notch at a time When using throttle reduction to slow/control train speed while cresting grade, continue to reduce throttle to o keep the speed from increasing until _____. 1. the leading wheels have crested the grade 2. at least half the train has crested the grade 3. the rear wheels have crested the grade 4. the lead locomotive consist has crested the grade - correct answer At least half the train has crested the the grade After reducing the throttle to Idle, wait 10 seconds before: 1. making split reductions 2. increasing braking to desired level 3. making the final brake reduction 4. activating the dynamic brake and bunching the slack - correct answer Activating the dynamic brake & bunching the slack At a sufficient distance from the stop, actuate, then make a ______ brake pipe reduction. 1. 6-8 psi 2. 2-3 psi 3. 10 psi 4. 15 psi - correct answer 6-8 psi When can you start supplementing with the independent brake? 1. once speed is below dynamic brake range 2. this is not allowed 3. once speed is below 20 mph 4. once dynamic brakes engage - correct answer Once speed is below dynamic brake range After reducing the throttle to Idle, you must _____ before actuating a making the minimum brake pipe reduction. 1. increase braking to desired level 2. wait for the slack to adjust 3. make split reductions 4. make the final brake reduction - correct answer Wait for the slack to adjust At a sufficient distance from the stop, actuate, then make a _____ brake pipe reduction. 1. 15 psi 2. 10 psi 3. 2-3 psi 4. 6-8 psi - correct answer 6-8 psi When do you make the final brake pipe reduction? 1. one speed is below 20 mph 2. as the train comes to a stop 3. before making the plot reduction 4. once speed is below the dynamic brake range - correct answer As the train comes to a stop A crew operating on a descending grade experiences a penalty brake application and comes to a stop. The independent brakes will hold the train on the grade. Is the crew required to tie hand brakes to recharge the air brake system? 1. no, if the independent brake will hold the train, no hand brakes are required. 2. yes, crews must always tie hand brakes to recharge a train on a grade. 3. the crew only needs to tie hand brakes if the grade they are operating on exceeds 1%. - correct answer No, if the independent brake will hold the train, no hand brakes are required. What should not be applied to hold a train stationary on a grade? 1. power 2. independent brake 3. dynamic brakes 4. air brakes - correct answer Power When necessary to use stretch braking, exceeding throttle position ____ is prohibited. 1. 1 2. 2 3. 4 4. 3 - correct answer 4 When is stretch braking permitted? 1.
