I would say that route locking is required here, bearing in mind that a train using one of these routes might come to rest in the platform and then have another train called-on behind it.
I have not been able to look at what was posted yet, but this comment caught my eye in Zaphod's post. It is correct to put the M and W as opposing the C (and indeed the other 2 combinations of these 3), but there is no release condition for it as it is not held once the first train has taken its route since the other routes are in the same direction. This is no different to over-setting a following route from any other signal.
