There were Sentinals and Claytons. The lner inherited the ner tyneside eletric stock which needed refurbishing in 1934 and was autherised to construct new stock. The eventual total was 164 multiple unit coaches made up into twins. These were then formed into various lengths as traffic demanded.
In 1925 the LNER introduced Steam railcars they were operated in small numbers until 1927 a batch of 11 was obtained from Clayton wagons Co these were opperated in the northe east. The LNER also purchased a number of trailer cars fro Clayton to increase passenger numbers on market day.
They were finished in simulated teak or Plum and cream but from 1930 they were finished in engine green and cream.
The Sentinals outlasted the the Clayton steam railcar so all the trailers were paired with the Sentinals.
By 1940 all had gone, a total of 81 Sentinal Cammell steam railars were purchased between 1925 and 1932 with various body designs including ridged bodied articulated and one articulated twin. All but 3 were named, the names were previously used on stage coaches. The Sentinal outlasted the Clayton by 8 years the majority withdrawn from 1943 the final one being in 1948
Ironically the last one was named "Hope"
