query: What railway lines in Buckinghamshire were developed in the 1830s?
answer: In the 1830s, sections of the West Coast Main Line and Great Western Main Line were opened in Buckinghamshire.  The London and Birmingham Railway (L&BR) and the Great Western Railway (GWR) were formed with the intention of creating lines through the county. The L&BR's line initially planned to go through Buckingham but was moved to Wolverton, with construction beginning in 1833. The GWR's line, beginning construction in the mid-1830s, opened in sections in 1838 and 1839.
