In 1872 the Stockton & Darlington Railway constructed two family saloons. As they were constructed after the NER absorbed the S&D they would have carried the later style S&D / NER garter crest. The original S&D carriage numbers are unknown but reviewing surviving records we estimate that they were probably 228 and 229. They ran in an attractive varnished teak livery with gold lining.
The S&D operated independently to the NER until the death of its Railway Superintendent Thomas Bouch in 1876. After this date it was finally absorbed into the North Eastern Railway. These vehicles probably continued to run in teak livery after 1876 until they were shopped and re-painted in standard NER crimson lake livery carrying new numbers 1662 and 1663.
No information survives regarding how far and wide they travelled however it stands to good reason that wealthy families could potentially have hired these carriages for excursions around the country.
