Some unusual coaches have recently been spotted tucked away in sidings on the railway.
The first of these was this Laboratory 14 coach, also named 'Wren'.
She is seen here in the middle road at Sueston station in the company of some other RTC liveried coaches.
This particular model is by Bachmann and it was commissioned by Modelzone in 2009.
Bachmann describe it as a BR Mk1 FK ex-Pullman Kitchen Laboratory coach and it has the Running Nº RDB 975427. The Catalogue Nº is 39-280Z.
The real Laboratory 14 was an acoustics test vehicle that was converted from a Metro Camel Pullman Car, Nº M323E, in 1975.
It was used to monitor noise levels and, for this, microphones and pressure measuring devices were attached to both the inside and outside of the coach.
Therefore, in order that the noise from the locomotive would not affect these measurements, it was often attached to the rear of service trains.
Sadly this coach was scrapped in 1989.
The next two coaches were captured in one of the bay platforms at Gunnmere Junction behind a Class 24.
They are a pair of Mobile Track Assessment Engineers' Support Coaches and were, again, commissioned by Modelzone, this time in 2008.
These coaches, I believe, formed part of the Network Rail/Serco High Speed Track Recording Train and each included a dormitory
As with Laboratory 14, these two coaches, I believe, were also scrapped, in 2008.
