Bachmann 35-625 OO Gauge Class 170/4 3 Car DMU 170412 ScotRail

The Branchline ‘Turbostar’ is back with this brand-new model that has been designed from the rails up to create a new star for the OO scale multiple unit fleet. Building on the success of the Branchline Class 158 with its low level, invisible drive train and comprehensive lighting suite, our new ‘Turbostar’ take things a step further with the addition of a Bach-Up Stay Alive System. Like the 158, a Plux22 DCC Decoder socket is located beneath a removable underframe panel and this controls all vehicles via the inter-car couplings which incorporate close-coupling mechanisms and multiway electrical connections.

The lighting features include directional lights with day/night modes and independent control of either end, a necessity when you’re working your units in multiple, which you can do thanks to the working miniature BSI couplings fitted to the outer ends, allowing the new 170 to couple in multiple or with other units like the Branchline 158s. Passenger saloon lighting is fitted as are illuminated destination panels, while DCC users can take advantage of the working door interlock lights, and cab lights too.

The model’s impressive specification is complemented by its good looks which are brought to life with the exquisite livery application, using authentic colours, logos and markings to create a showpiece model worthy of any modern collection.

CLASS 168/170/171 ‘TURBOSTAR’ DMU HISTORY

The ‘Turbostar’ Diesel Multiple Units (DMUs) were built by ADtranz (which later became Bombardier Transportation) at the historic Derby Litchurch Lane Works. The ‘Turbostars’ are a family of DMUs that share a modular design, much of which was derived from the earlier Class 165 and 166 DMUs which came from the ‘Networker’ family of units.

Construction of the first ‘Turbostars’ began in 1997, shortly after the Privatisation of British Rail, with Chiltern Railways placing the opening order for new units that would go on to be known as the Class 168s. The first vehicles to be outshopped used ‘Networker’ style cabs as the new cab design was still being finalised and these units were allocated Class 168/0, whereas later builds which used the new ‘Turbostar’ cab were Class 168/1 and 168/2. The Class 168s were fitted with BSI couplings at the outer ends, with electrical connections that were compatible with the Class 165 and 166s that Chiltern had inherited from Network SouthEast.

The first Class 170 units were ordered by Midland Mainline with deliveries commencing in November 1998, the first units entering service in May the following year. Like the 168s, the Class 170s were fitted with BSI couplings but with standard electrical connections, allowing them to work in multiple with Class 14x and 15x units. Construction took place over a seven year period at the end of which 139 units had been delivered in either 2-car or 3-car formations for multiple operators around the UK. Subclasses have been used to differentiate between the various seating and interior layouts specified by different operators.

Concurrent with production of the Class 170s, Southern ordered a fleet of Class 171s that were delivered as 4-car units in 2004. These differed from the 170s by having Dellner couplings instead of the BSI type at the outer ends, along with electronic destination panels on the bodysides. Southern had taken delivery of some 2-car Class 170s a year earlier and these were subsequently fitted with Dellner couplings and reclassified as 171s. In more recent years, inter-operator transfers have seen the Southern fleet expanded with further 170s which too have been converted to 171s with the fitting of Dellner couplings.

Today, the ‘Turbostars’ are still in daily frontline service across the UK, working on both regional and long distant services for which they remain well suited thanks to their 100mph top speed. Class 168s and 171s are still operated by Chiltern and Southern respectively, whilst current operators of the Class 170 fleet include Cross Country, East Midlands Railway, Northern and ScotRail.
