6 CAST your eyes upwards to admire the wonderful Victorian brick and stone archways carrying trains between Worcester and Hereford.

But has Railtrack noticed the menace from young sycamore, ash and buddleia vigorously growing in the vertical brickwork?

Walk down Cherry Tree Walk and The Butts and take a look.

Already, two chunks of stone have fallen - do workshops beneath these arches realise these dangers?

It's no good Railtrack doing a cheap cosmetic job by cutting off all visible foliage, because roots will continue to flourish and do unseen damage. The cracks will widen.

Worcester City Council and Severn Trent have much evidence of ruptured walls near Worcester City Bridge.

The cause? Fifteen years of failure to remove alder self-sown trees from the River Severn's walling.

If Railtrack does nothing, my daily journey from Foregate Street Station to Malvern Link will be replaced by a bus journey.
