Three out of the four locos available for roster are ancient ReplicaRailways products.
It was decided early on that the cheapest option, except the Hornby example, would be used to minimise cost.
The exception is a Bachmann latest chassis example obtained cheaply due to incorrect boxing!
You can tell the difference by looking at the wheels!
This one is the exception- a 8750 pannier. It admittedly run better but usually 3 times the cost of the others so it should.
Some spares were obtained from Replica and some spare gears from Peters Spares which have given a new lease of life to them.
All bar 3635 , which is the haulier of the 4 wheel coaches, are all fitted with loops for Spratt and Winkle couplings which are a feature of the GWR stock on St Mewan.
