Note: All information in the Crossing Details tabs is read only for railroad users.
1. No Signs or Signals - Select "At Least One Sign or Signal" or "No Signs or Signals" from the dropdown. If no signs or signals are present, there is no need to complete Items 2 or 3.
2. Type of Warning Devices at Crossing - Passive Signs (Specify Number of Each)
NOTE: If more than one type of warning device is present, indicate all applicable types of warning device(s). Enter a "9" where the number is 9 or greater. Provide short descriptions of "Other" devices in the appropriate spaces.
2.A. Crossbucks - Enter the number of masts with crossbucks, not a count of all crossbuck signs. Two or more crossbucks mounted on a single mast are counted as one crossbuck. Include in the count all masts with crossbucks, without making a distinction as to the reflectivity type.
2. B. Highway Stop Signs (R1-1) - Enter the number of Standard Highway Stop Signs (this is the MUTCD specified Stop Sign, R1-1). A standard highway stop sign is red with white letters and has eight sides as defined in the Manual on Uniform Traffic Control Devices (MUTCD). Any other non-standard MUTCD stop signs should be listed in the field for “Other Signs.”
2.C. RR Advance Warning Signs (W10-1) - Select "Yes" or "No" from the dropdown to indicate the existence of advance warning signs along the highway approaches that are in compliance with the MUTCD (normally, would be on both sides).
2.D. Hump Crossing Sign (W10-5) - Select "Yes" or "No" from the dropdown to indicate whether or not high profile hump surface signs are present at the crossing or such are scheduled for installation in the immediate future. The standard Advance Warning Signs for High-Profile Crossings is identified in the MUTCD as W10-5. Non-standard warning signs or advisories should be listed in “Other Signs.”
2.E. Pavement Markings - Select the appropriate radio button for the type of pavement marking present that conforms to the MUTCD. If both stop lines and RR crossing symbols are present, select "Stoplines and RR Xing Symbols." If neither stop lines nor RR crossing symbols are present, select "No Markings."
2.F. Other Signs - Enter the number and specify the type of any other passive signs at crossing. Specify MUTCD Type. Non-standard stop signs should also be reported in this item.
3. Type of Warning Device at Crossing - Train Activated Devices (Specify Number of Each)
3.A. Gates - Enter the count of gates. Include in the count all gates without making a distinction as to the color or reflectivity of the gate or arms.
3.B. Four-quadrant (or full barrier) Gates - Select "Yes" or "No" from the dropdown to indicate whether or not four-quadrant (or full barrier) gates are present at the crossing. Full barrier gates apply in the case of 1-way streets or where the gate arms reach across the entire roadway.
3.C. Cantilevered (or Bridged) Flashing Lights - Enter the number of cantilevered (or bridged) flashing lights in the appropriate block. Separate cantilevered flashers from those over traffic lanes and those not reaching the roadway (over only parking lanes, turnout lanes, or shoulders). Count individual cantilever units; do not count the flasher head pairs mounted on the units.
3.D. Mast Mounted Flashing Lights - Enter the number of mast mounted flashing light units. Count all flashers on a single mast as one flasher. Do not count flasher heads or a pair of flashing lights separately.
3.E. Number of Flashing Light Pairs - Enter the total number of pairs of flashing lights mounted on signal masts in Item 3.D. and on cantilever (or bridge) units in Item 3.C. and/or on other masts or poles.
3.F. Other Flashing Lights - Enter the number of other flashing lights not in accordance with the MUTCD. Specify type.
3.G. Highway Traffic Signals - Enter the number of highway traffic signals (red-yellow-green signals) that are train activated and which control street traffic over the crossing. Do not count highway signals controlling a nearby intersection even if they are interconnected with the crossing devices.
3.H. Wigwags - Enter the number of wigwag signals.
3.J. Bells - Enter the number of all bells, if present, that are either alone or in conjunction with other train activated warning devices.
3.K. Other Train Activated Warning Devices - List any train activated devices not otherwise specified, such as an arrester net, dragnet or other new technology.
4. Specify Special Warning Device NOT Train Activated - Enter the type of any special warning device which is not train activated. Examples of special warning devices not train activated are:
a. Manually operated signals and/or gates
b. Train crew flagging the crossing
c. Watchmen
d. Floodlights (may be train activated)
For watchmen and for manually operated gates, the number of hours daily in effect should also be indicated. For floodlighting, the number of masts with lights should be reported. Only floodlighting which is distinctive from other ordinary street lighting in intensity, light distribution, focus or color is to be reported.
5. Channelization Devices With Gates - Select the appropriate radio button to indicate whether or not there are channelized devices (i.e., median barriers) with gates at the crossing and whether they are on all approaches or just one approach.
6. Train Detection - (READ ONLY) Indicates the type of train detection used at the crossing. Choices are:
Constant Warning Time (or Predictors)
Motion Detectors
DC/AFO
Other
None
The following apply to active crossings only: Constant Warning Time, Motion Detectors, DC/AFO, or Other. If the crossing is not active, “None” should be checked.
7. Is Track Equipped with Train Signals? - (READ ONLY) Indicates whether the track has train operation or interlocking signals to control train operations.
8. Traffic Light Interconnection/Preemption - Select the appropriate radio button to indicate the type of crossing interconnection/preemption.
The following are definitions for highway and rail signal interconnections. The definitions which are in italics are those defined by the Technical Working Group (TWG) on Rail-Highway Intersections:
Interconnection: The electrical connection between the railroad active warning system and the traffic signal controller assembly for the purpose of preemption
Interconnection consists of an electrically connected control circuit at a highway-rail intersection which has railroad active warning devices utilizing a supervised closed-circuit principle activated by the approach or presence of a train and which is used to preempt the normal operation of a highway traffic signal.
Preemption: The transfer of the normal operation of traffic signals to a special control mode.
Preemption is the activity when, as a result of a signal received from the railroad active warning device system, the normal operation of a highway traffic signal is interrupted and transferred to a specific programmed sequence.
Simultaneous Preemption: The notification of an approaching train is forwarded to the highway traffic controller unit or assembly and the railroad active warning devices at the same time.
Simultaneous Preemption is the activity when the highway traffic signal controller receives notice from the interconnection control circuitry and is activated at the same time as the railroad active warning system. Usually, this will be used to prohibit highway vehicular traffic from traversing through the crossing intersection.
Advanced Preemption: The notification of an approaching train is forwarded to the highway traffic controller unit or assembly by the railroad equipment for a period of time prior to activating the railroad active warning devices.
Advance Preemption is the activity when the highway traffic signal controller receives notice from the interconnection control circuit before the railroad active warning system is activated (usually 20-25 seconds before train arrival) to interrupt the signal’s normal operation to begin its specific programmed sequence. Usually, this will be used to move the highway vehicular traffic through a storage area between the highway-rail intersection and the highway-highway intersection well before the railroad active warning devices start to operate to clear the crossing and eliminate the potential of vehicular entrapment on the crossing.
