I must admit I haven't been over the Cleveland line in quite a long time. The angle was in place for turning locomotives before electrification of the lines. I'm not too sure if the track at the angle is still in place, but DEL's usually don't go past Lytton Junction. The track past Thornside was only listed for overheads around 1986-1987.
I have corrected the spelling mistake, and I will be posting another updated page with quite a few updated names etc., very soon
