This is from a later edition of the Walker Brothers famous beautifully engraved The British Atlas of 1837. 'An interesting feature is that the maps were usually issued with all railways built marked in red by hand. Often these red railways are more extensive than lines actually engraved on the maps since old stock could be used up whilst still claiming that the maps contained the latest information.' (David Smith Antique Maps of the British Isles p.213)
