= Overview =
The List Clean Consist (L) command on the System Menu lists train information in a generic format. You may also choose from the following four alternative formats for displaying header and tag information:
*S-918A Format (formerly known as T94)
*Full Consist Format
*Compass Format
*TCS Format
The following tables explain the screen data that displays with each format. The format options are listed below with their appropriate commands in parentheses, followed by header and tag segment definitions. For instructions on using the commands, refer to [[APU-102 User Interface]].
= S-918A Record Format (LT94) =
<p>For detailed, up to date information on the S-918A specifications refer to the AAR’s ''Manual of Standards and Recommended Practices, Railway Electronics, Section K.''</p>

|   <p>Description of Data</p>
|- 
|   <p>RRE</p>
|   <p>Rail Equipment (car and locomotive) Identifies tagged and untagged locomotives and railcars. Provides information about where the vehicle is in the train, which direction it is facing and its ID (if tagged). Also reports any inaccuracies that are seen when processing the car. At least one RRE is sent for each rail vehicle on the train. A second RRE is sent when two tags found on a vehicle have different IDs (called a ID mismatch). The RRE segment is always the first segment reported for each vehicle.</p>
<p>Format</p>
<p>∙ Sequence Number. (3 numeric) Standing order of the vehicle in the train (1 = first).</p>
<p>∙ EGC Number. (1 alpha) Based on axles if tags are missing or have wrong EGC. If axles are also suspect, EGC = ?. Values:</p>
<p>D = Locomotive</p>
<p>R = Railcar (and former Non-Revenue Rail)</p>
<p>? = Unknown</p>
<p>∙ Equipment Initial. (4 alpha) Standard Carrier Alpha Code as read from tag. Blank if not tagged.</p>
<p>∙ Equipment Number. (10 numeric) Number of equipment as read from tag. Zero (0) if not tagged.</p>
<p>∙ Orientation. A = A end forward, B = brake end forward, U= unknown or not determined</p>
<p>∙ Field Reserved for Future Use. (1 character)</p>
<p>∙ Axle Conversion Code. (1 alpha) Values:</p>
<p>G = Good. No problem reading axle input.</p>
<p>B = Bad. Axle information may have caused an extra vehicle.</p>
<p>S = Sequence Logically Correct. Not an extraneous vehicle, but may be misidentified.</p>
<p>∙ Tag Detail Status. (2 alpha) Accuracy of tag information.</p>
<p>&nbsp;First character:</p>
<p>G = Good; tag data okay</p>
<p>M = Mismatched identification (Owner code and equipment number only)</p>
<p>L = Left side is bad.</p>
<p>R = Right side is bad.</p>
<p>C = Candidate platform. Software has detected that the target car may be part of a multipack, but is reported as an independent car.</p>
<p>N = No tag read.</p>
<p>? = Other</p>
<p>Second character:</p>
<p>I = Individual platform tags, multi-packs incorrectly tagged.</p>
<p>K = OK</p>
<p>A = Axle error, number of axles in tag differed from axle pattern.</p>
<p>B = Bearing error</p>
<p>D = Unused tag read on equipment.</p>
<p>E = Equipment Group Code error, EGC in tag differed from axle pattern.</p>
<p>H = Performance, handshakes less than that predicted by Amtech speed and range guidelines.</p>
<p>L = Length error. Length in tag differed from axle pattern.</p>
<p>M = Multiple errors.</p>
<p>O = Orientation errors. Tag applied on wrong side or wrong end of equipment.</p>
<p>P = Platform code error. A multipack car had a bad platform code or a non-multipack car had a platform code.</p>
<p>W = Window violation. Tags applied outside the AAR window for acceptable application.</p>
<p>? = Other</p>
<p>∙ Hand Shakes Antenna 0 (2 numeric) 99 = 99 or more.</p>
<p>∙ Hand Shakes Antenna 1 (2 numeric) 99 = 99 or more.</p>
<p>∙ Speed of Vehicle. (MPH or KPH)</p>
<p>∙ Axle Count. (2 numeric) Number of axles found on the car.</p>
<p>∙ Platform Count. (2 numeric) Number of platforms on the car.</p>
