  We consider free-fermion chains where full and empty parts are connected by a
transition region with narrow surfaces. This can be caused by a linear
potential or by time evolution from a step-like initial state. Entanglement
spectra, entanglement entropies and fluctuations are determined for subsystems
either in the surface region or extending into the bulk. In all cases there is
logarithmic behaviour in the subsystem size, but the prefactors in the surface
differ from those in the bulk by 3/2. A previous fluctuation result is
corrected and a general scaling formula is inferred from the data.
