PARTIES - Brotherhood of Maintenance of Way Employes
 .DI3TUTE : and
 Baltimore and Ohio Railroad Company
 STATEMENT Request that J. W. McKenny be restored to his fore
 OF
 CLAIM : man's position with seniority unimpaired and be
 allowed the difference in rates of pay from Novem
 ber 3, 1978 until so restored.
 FINDINGS : On August 15, 1978, Engineer of Track Archinal and
 Assistant Supervisor Cregger went to the Calvert
 Street Tunnel to observe the work of claimant's
 track gang. A slow order placed on the main track
 of that Tunnel on June 17, 1978 had not been removed
 by August 15, 1978 and Mr. Archinal considered it
 important to observe the activities of claimant's
 gang at their work site. His visit was certainly
 reasonable and consistent with his responsibilities.
 It is his testimony that claimant's gang did not
 reach the job site until 9:10 a.m. and then were permitted to take
 their lunch from 10:35 a. m. until noon. Mr. Cregger corroborated
 that testimony in essential particulars. Their testimony is credible
 2--77g _q and specific; though controverted by claimant and members of his gang, it is sufficiently substantial to support Carrier's findings and in line with numerous awards this Board will not disturb them. It is not within our province to resolve questions of credibility. As an appellate board, we have no opportunity to observe the conduct and demeanor of the witnesses or to hear them. .
 There is no evidence that claimant was singled out for unfair treatment or that Carrier committed prejudicial error. In the light of these considerations, the findings and the entire record, we find no persuasive basis for substituting our judgment for that of Carrier in the demotion of a supervisory employe.

 AWARD:

 Carrier Member

 Claim denied.
