'Wall being built around bomb'published at 09:06 British Summer Time 16 May 2017
We've been telling you this morning about possible day-long cancellations of Cross City line services between Birmingham and Lichfield following the discovery of a World War Two bomb at a site in Aston parallel to a stretch of the route.
National Rail has been updating its information, external and reporting details of the operation to make safe the device.
According to its website the "unexploded bomb needs to be safely detonated and in order to do this, a wall needs to be built around the bomb first.
"This is expected to take a number of hours to build and once the bomb has been safely disposed off [sic] the infrastructure in the area then needs to be carefully checked before the line can reopen."
