Right, speed limits and track identification added to the:
Heath Town Branch [Wolverhampton]
Darlaston Chord [Walsall]
Round Oak Branch [Stourbridge/Brierley Hill]
Soho Bank [Birmingham]
Will aim to finish off the Cross City line tonight - Redditch Branch has no speed limits at the moment, nor the bit of the Cross City North from Sutton Coldfield to Lichfield.
