Z Gauge Code 60 - Small Scale Flexible Track
A gauge of just 6.5mm and a model scale of 1.5mm/1ft means if you want to model big landscapes where the trains are dwarfed by the scenery and yet keep it to a manageable size, Z gauge could be the answer.

For adding 3rd and 4th Conductor rails to existing track as found on Southern, Merseyside and London Transport systems, for example. Use IL-1 Code 60 rail with these chairs

These wagon and van kits are very quick and easy to assemble. Consisting of a one-piece pre coloured body moulding, chassis, chassis weight, disc wheels and couplings, they are essentially unpainted, unassembled versions of our famous ready to run range.

12 cosmetic fishplates to use at joints between Code 124 and Code 143 rails.

The pre coloured parts of this plastic kit can be assembled in a number of ways; further kits can be combined to make a larger structure if required.

A superb auto coupling designed for magnetic operation using the special uncoupler SL-32
‚Ģ Allows a vehicle to be lifted straight from within a train without derailing adjacent vehicles
‚Ģ Delayed action feature - after uncoupling, a vehicle can be pushed to any position
‚Ģ Supplied complete with spring, screw and adaptor moulding

The original metal coupling designed for use with the SL30 uncoupler, allows a vehicle to be lifted straight from within a train without derailing adjacent vehicles.

Part of the range of Peco wheels and couplings for use by kit builders and scratchbuilders.

Each pack contains 4 loads; as supplied they each fit a standard wagon. The mouldings are designed to be split in half so that one and a half mouldings can be used to fit a 15ft open wagon.

Private owner wagons abounded prior to nationalisation, they would often be seen far from their base as they were sent to collect raw materials and supplies such as coal, and deliver finished goods. All Peco wagons feature free running wheels in pin point axles. The ELC coupling, whilst compatible with the standard N gauge couplings, keeps a realistic distance between vehicles and enables the PL-25 electro magnetic decoupler to be used for remote uncoupling.

This crossing is designed to be used with the ST-6 Left Hand Turnout to make a crossing within the standard Setrack geometry. PECO Setrack N Gauge Code 80 - Unit trackage System
The high quality rigid unit trackage system suitable for all popular brands of N gauge model trains.
Being fully compatible with both Code 80 and Code 55 PECO Streamline, it need never be discarded as your layout develops.
The solid nickel silver rails are integrally moulded into the sleeper bases for maximum realism and strength. Turnouts are fitted with an over-centre spring for immediate use, no extra levers necessary.

Peco Streamline Code 75 track meets the standards of enthusiasts who prefer to run trains on scale height rail. Today most manufacturers' wheels are suitable for use on Code 75 track but some vintage models may have flanges which are too deep to clear the rail fixings. Code 75 can be easily combined with code 100 track by using the SL-113 Transition Track.

The wide range of turnouts and crossings in this series includes every type, and the geometry of this range has been cleverly designed to make it easy to build convenient, complex and aesthetically pleasing formations using combinations of small, medium and large radius turnouts and crossings. Layout plans suggestions can be found in our publications ‘Track Plans for Layouts to Suit all Locations’ (Ref PM-202), ‘60 Plans for Small Railways’ (Ref no PB-3), and ‘Track Plans for Various Locations’ (Ref no PB-66).

Double slips can save valuable space at station approaches, junctions etc.

If you wish to mix wheel standards on your 00/H0 layout, this is the trackage to choose. Code 100 rail allows flange depths up to 1.6mm which means that both vintage and current stock will run happily together.
