Long Island Rail Road

Updated: 2 days ago

Can anyone help with dating the survey for this beautiful map of Long Island with the Environs of New York and Southern Connecticut?  Clearly the publication date of 1836, is not the same as the survey dates – they rarely are.  The map would have been compiled ‘from surveys..’

The map was published by J.H.Colton the famous publisher of maps of America in 1836 and this edition of the chart is dated 8 years before any other edition I can find in either American Public Record houses or even in the catalogues of antiquarian map dealers.  It is certainly in a near pristine state.

The surveyor was J. Calvin Smith

One of the most obvious ways to date the original survey is to look at the development of the railways and the LIRR is an obvious starting point.

The question is:  At what date did the LIRR get to this point?

All help gratefully received.
