 There seems to be a George E. Archer who was based in New York City and was an architect for the railroads. He is not the same as George Archer of Baltimore. I found George E. Archer's name in the compiled city directory listings from the book Architects in Practice, New York City, 1840-1900. A copy of the entry is attached. It shows a death date of 1903. George E. Archer was not an AIA member, so I don't have any further information about him. 

 The lead provided was from  which states that George E. Archer (d.1903) was Supervising Architect, Erie RR, does considerable outside work, resident Passaic 1899-1901.
