Moulded track sleepering enables the creation of additional types of turnouts for 0-16.5, using items from the 00 Streamline range.

16.5mm gauge track in 7mm scale gives an equivalent prototype of 2ft 4 ins, making it a popular choice for modellers, this scale is also known as 0n30 in the USA because this results in a prototype gauge close to 30ins. Many modellers find that this scale/gauge allows an ideal combination of scale detail in a relatively small space.
