High-class field set for Railway Stakes Royal Ascot juvenile form could get an early test in Saturday's GAIN Railway Stakes at the Curragh. Coventry Stakes runner-up Cappella Sansevero and Chesham second Toscanini could do battle in the Group Two. It was a first defeat in four races for the Ger Lyons-trained Cappella Sansevero in Berkshire and he could be joined by stablemate Dandyleekie. Mick Halford's Toscanini has yet to win a race but has shown classy form on a number of occasions. Aidan O'Brien's juveniles did not perform to their usual standard last week and three of them - The Great War, who finished fifth in the Norfolk Stakes, Chesham third Dick Whittington and War Envoy, ninth in the Coventry - could aim to redeem their reputations. O'Brien may also run Battle Of Marathon, Rule The Waves and As Good As Gold. Peter Chapple-Hyam supplemented Ahlan Emarati after his third-placed finish in the Norfolk. Richard Hannon's Kool Kompany, a Listed winner at Naas but unplaced in the Coventry, is another possible, as is Michael O'Callaghan's promising Rapid Applause.
