Further information from Mr J Thickitt:

The nearest engines on the siding on the left had hessian sacking over the top of their chimneys showing they were no longer in regular use. Possibly this appearance indicated an 'in store' status (the railway term meaning held in reserve in case - or because - they were needed at a later date). By the mid-1960s engines 'buffered-up' in sidings as here would sometimes be redundant, waiting to leave the shed for an appointment with a cutting torch! Should all the engines on one or both of these tracks have been condemned they would have been on what was unofficially known as the 'scrap-line'.

Other engines sheltering inside the shed were some of those still active; Darnall shed closed to steam in 1963, becoming a diesel depot for a time.

Mr Thickitt remembered seeing multiple-unit sets and the occasional diesel locomotive here, later these being replaced by rows of waggons.

The heaped row between the lines of engines was probably locomotive coal.
