Over time CPR influence dominated, partly because their short trains and small locomotives suited modelling constraints. However, CN enthusiasm is renewed with each delivery of the fine CN Lines publication.

Construction techniques have varied over time as skills, knowledge, and available resource materials improved. Engineering standards have been quite consistent, reflecting satisfaction with the reliability delivered from the start. The original “spaghetti bowl” is code 100 Peco track with 9 Shinhara and 11 hand laid turnouts. Subsequent more prototypical expansions employed code 83 Micro Engineering and hand laid track, and an additional 24 hand laid and 6 ME turnouts. Eased, super-elevated track has contributed to reliable operation. The original plan made provision for connections to the expansions that followed.
The four control panels employ a simple and robust electrical architecture that has reliably stood the test of time. It is however archaic, and is not particularly well suited to intuitive operation on the increased extent and complexity of track work. It works reliably, but takes a while to learn!
The rugged terrain has yielded opportunities to scratch build interesting civil works, including numerous trestles and bridges, and a snow shed. Most line side buildings and the Fife tipple are scratch built, whereas the engine service facilities are mostly kit-bashed.
