Before Christmas it was discovered that our newly acquired Aa type bogies had had their axle box covers opened and packing removed. The only conclusion that we could come to was that someone was inspecting the axel boxes with a view to returning and stealing the plain bearing brasses, right or wrong as this assumption might have been, we have since removed all brasses and stored them securely elsewhere. Better to be safe than sorry, on the up side the bearings confirm the bogies as those from an Aa.
