Radiorails. I did get a photo of sister XHA 482 (now at Wythall) so I suppose that will have to do.Not sure if anyone has a better photo; you can live in hope I guess.
XHA 453 (4453), BMMO D7 type entered service December 1955. It stayed operational until October 1971. 1st depot was Bearwood BD, then DH in 12/58. Back to BD in 1/59. LW in 8/66 and finally SE 2/70.
