CWR
Rail exceeding 400 feet
What is continuous welded rail(CWR)?
Rail length that exceeds 400 feet is considered CWR. Rail installed as CWR remains CWR, regardless of whether a joint or plug is installed into the rail at a later time
System used to monitor position of on-track equipment.
What is HLCS?
MWOR 6.50.5 Hi-rail Limits Compliance System (HLCS):
The Hi-rail Limits Compliance System (HLCS) is a safety system designed to monitor the position of HLCS equipped on-track equipment. On subdivisions where HLCS is in effect, all HLCS equipped on-track equipment fouling or occupying the track authorized by Track and Time, Track Warrant or Track Permit must be associated with the authority and the system must be activated, including within Form B limits. However, HLCS cannot be associated with a Track Bulletin Form B. The HLCS thumbwheel must be set to indicate the authorized track when the equipment is fouling that track.

What is Urine?
Split or otherwise impaired so that it will not hold spikes or other rail fasteners
What is a defective tie?
EI 7.2.1 B
A wood cross tie is defective when it is:
● Broken through.
● Split or otherwise impaired so that it will not hold spikes or other rail fasteners.
● Deteriorated so that the tie plate can move laterally more than 1/4 inch relative to the cross tie.
● Cut by the tie plate more than 1 inch.
● Cut by wheel flanges, dragging equipment, fire, etc., more than 2 inches deep within 12 inches of the base of the rail, frog, or load-bearing area.
● Rotted, hollow, or deteriorated with a lot of wood decayed or missing; hollow under plate area.
the proper anchor pattern to use in a turnout and how far should that pattern extend in either direction?
Turnouts should have every tie solid box anchored for 195 feet in either direction
(Where possible, anchor a turnout with eight anchors on each switch tie. Apply this pattern to both welded and bolted turnouts).

What is a flagging kit?
MWOR 5.2.3 Flagging Kit:
All hi-rail vehicles, on-track equipment that works independently, and the lead and trailing pieces of on-track equipment in a gang consist must carry a complete railroad flagging kit. Vehicle operators whose duties may require flagging must carry a complete flagging kit in the vehicle. The employee in charge and the machine operator are responsible for ensuring that the kit is complete at the beginning of each shift. A complete flagging kit consists of the following: 12 - Red Fusees 2 - Red Flags 2 - White Lights
Two most significant processes the body uses to cool manage and heat
What are routing blood flow to the skin's surface and cooling through sweating?
progressive fracture originating from a center or nucleus in the rail head that propagates in the transverse plane as a smooth, bright or dark
What is a tranverse fissure?
EI 6.7.3 Defect description
Transverse Fissure (Type 15) A progressive fracture originating from a center or nucleus in the rail head that propagates in the transverse plane as a smooth, bright or dark, and round or oval surface, substantially at a right angle to the length of the rail. Features that distinguish a transverse fissure from other types of fractures or defects are the center or nucleus and a nearly smooth surface of development that surrounds it. This type of defect can only occur in the rail head. Rail zone should be specified as either 1 – Head Gage Side or 2 – Head Field Side.
Provide 2 examples of conditions that would warrant lengthening a temporary speed restriction
4.3.5 Lengthening Restriction Limits When necessary and when conditions could cause heavy braking too close to a temporary speed restriction, lengthen the temporary speed restriction limits by at least 0.2 mile before and at least 0.2 mile after the area of the speed restriction. Consider the following conditions:
● Rail temperatures at or above Target Neutral Temperature
● Recently disturbed track
● Descending grade
● Approaches to any fixed object
● Sharp curves
Utilizing a train's authority for protection
What is Train Coordination?
MWOR 6.3.4 Train Coordination
Train Coordination provides for men and equipment to use a train’s authority to establish working limits for track maintenance. The employee must contact the train’s engineer to request use of Train Coordination.
To establish working limits:
• The train must be in view and stopped.
• The employee in charge of working limits will communicate with the engineer who will notify other crew members that working limits are to be established.
• The engineer will make movements only as permitted by the employee in charge until the working limits have been released to the engineer. • The train will not release its authority within the limits until those working limits have been released by the employee in charge.
This environmental factor decreases evaporation
What is Humidity?
True or False:
Dynamic track stabilizers compact but can not consolidate the ballast to reduce slow order requirements associated with the surfacing.
False
EI 8.6.2
B. Raising Tracks
Dynamic track stabilizers compact and consolidate the ballast to reduce slow order requirements associated with the surfacing.
True or False
Spot and out-of-face work activities involving tie renewal, undercutting, and/ or surfacing without Dynamic Track Stabilizer for TNT + 20 degrees and over require 5 trains at 30 mph before raising to 45 mph
False
EI 4.10
Table 4-2
2 trains at 15 MPH. If track is OK after each train, then 4 trains at 15 MPH. If track is OK, then 4 trains at 30 MPH. If track is OK, then 10 trains at 45 MPH. If track is OK, then maximum authorized speed.
cars to move under their own momentum by releasing brakes or uncoupling the cars from other equipment.
What is a Gravity Move?
MWOR 7.7 Kicking, Dropping or Gravity Movements of Cars
When positioning cars, do not:
• Uncouple cars from moving self-propelled equipment
• Permit cars to move under their own momentum by releasing brakes or uncoupling the cars from other equipment.
True or False
Heat stroke is occurs when the bodies temp is over 106 degrees?
False
Body temp over 104 degrees is a sign of heat stroke.
True or False:
If a rail end shows a chip less than one-third the depth of the ball and 5 inches back from the end of the rail before grinding, the rail should be replaced instead of welded
False
EI 11.9 Rail Ends
11.9.1 General Repair Guidelines :
2. If a rail end shows any of following conditions, the rail should be replaced instead of welded:
● A vertical split head
● A crushed head
● A horizontal split in the rail head longer than 4 inches
● The repair will require welding beyond the end of the last bolt hole
● A chip greater than one-third the depth of the ball and 5 inches back from the end of the rail, before grinding
Welders arrive to a 5in rail added location. Knowing that a 5in pull is unfeasible they decide to use the destress process. Following the steps in the CWR procedure, they first cut the rail and then knock anchors for 200 feet in each direction. The welders took a rail temperature of 90 degrees on a subdivision with a TNT of 120 degrees.
What is the required pull amount
The required pull amount is 1in
All employees not part of this crew must determine if "this" is activated.
What is Remote Control Zone (RCZ)?
MWOR 6.7 Remote Control Zone (RCZ)
A. Entering Remote Control Zone
Before entering a RCZ, all employees that are not part of the remote control crew must determine whether the RCZ is activated. Employees may receive this information from the remote control operator, other authorized employee, or special instructions. When the RCZ is activated, tracks within the RCZ must not be fouled with equipment, occupied, or switches operated until the RCZ has been deactivated. Lone workers using individual train detection or work groups utilizing a lookout may perform minor work and routine inspections within an active RCZ but may not operate a switch.

Fall Restraint-Specialized equipment that will arrest a fall in progress before a worker reaches the ground or water surface, or any other obstruction below
False:
EI 1.4.2 Job Preparation
Four basic categories of fall protection in order of preference are:
● Conventional Fall Protection. Passive means of preventing a worker from falling from elevation; e.g. handrail system, ladder cage system.
● Fall Restraint. Selecting, arranging, and using fall protection equipment— such as an anchor, lanyard, and body holding device—in a manner that does not allow a worker to reach a location where a fall from elevation can occur.
● Fall Arrest System. Specialized equipment that will arrest a fall in progress before a worker reaches the ground or water surface, or any other obstruction below.
(Personal Fall Arrest System. A system used to arrest the fall of an employee from a working level. It consists of an anchorage, connectors, body harness, lanyard, shock-absorbing device, lifeline, or combination of these.
