PLR Model Size and Statistics

I have often been asked the overal size of the PLR so I have included the following plan of the current configuration. This can be compared to the configuration in the 1990s and 1980s.

The key statistics are:

Overall Size: 18ft x 14ft

NG full circuit: ~ 80ft
NG mainline maximum grade: 1 in 28 (3.5%) - from lower tunnel exit to quarry loop
NG mainline minimum radius: 27in - the big spiral and a small section c. 22in between quarry and viaduct.
The quarry lines are much steeper and tighter.
SG end to end length: ~30ft
SG maximum grade: 1 in 25 (4%) - mainly in hidden track

Grid squares = 1ft 

The plan below shows the section that was exhibited at ExpoNG 2014 with the additional boards that were built to allow operation:

PLR Location and Route

The following maps show the location of the three phases of the Pentewan Railway. The PLR was the third epoc* and the approxomate area modelled is shown below.

(* The PLR of course only really existed in my model world)
