LNWR Precursor 4-4-0 No 5308 Simoom with the 4.35pm up Birmingham two-hour express approaching Tring in 1930.
The leading coach is an interesting example of an ex LNWR double ended brake composite corridor to D205 or D207. Only about 20 of these coaches were built between 1907 and 1910. Note also the magnificent ex LNWR dining car as third vehicle .
