Manufacturer description

Locomotive 21C1 'Channel Packet' was the first of the Merchant Navy class, entering service in 1941 at Salisbury and then Exmouth Junction from 1942. Renumbered '35001' under British Railways in 1948, 'Channel Packet' was allocated to Stewarts Lane from 1957 until rebuilding in 1959. 

This model features DCC sound and steam functionality to recreate the first of Bulleid’s powerful and iconic Merchant Navy locomotives in the most authentic way. 

Detail features: 

• Highly detailed OO gauge model based on extensive research and original works drawings 
• Highly detailed cab with fully decorated backhead and decorated instrument dials 
• Opening cab roof vent 
• Removable simulated coal load with fully detailed tender bunker
• Accurately modelled Merchant Navy Bullied-Firth-Brown wheels
• Early 21C1 'widows peak' front end streamlining and chimney arrangement
• 5000 gallon tender in its original condition with raves yet to be cut back
• Cast trailing truck
• Separately fitted nameplate, number plate, and company ownership plate
• Horseshoe smokebox door company plate 
• Sprung metal buffers
• Heavy die-cast chassis, pony truck, and trailing truck 

Electronics and traction features: 

• Pre-fitted steam generator system featuring an optical sensor for accurate chuff rate synchronised with the wheel speed. Steam output is created using piezo element technology. This is a cold water-based system (no heating element). 
• Pre-fitted 21-pin HM7000 decoder and speaker. The decoder is compatible with NMRA DCC controllers and HM7000 app control. 
• Pre-installed Merchant Navy sound profile for accurate locomotive sounds, synchronised with the chuff rate and steam effect.
• Adjustable steam output settings via the decoder 
• Water reservoir for up to 20 minutes of continuous steam running
• Die-cast connecting rods and valve gear 
• Powerful 5-pole skew-wound motor 
• Flywheel with cardan shaft arrangement for smooth running 
• Oilite main drive bearings 
• Wheel pickups on tender and driven locomotive wheelsets 
• Pogo pin wheel pickup arrangement for easy pickup servicing 
• 8-way locomotive to tender drawbar, with integrated electrical connection for easy coupling and decoupling.
• Front and rear NEM coupling pockets, with narrow tension lock couplings 
• Optional fit rear flanged wheelset (only recommended for larger layouts with sweeping curves or display purposes).

Prototype information

^* Class names often change over the lifespan of a locomotive, so this is not necessarily the class name used by the operator in the period modelled.

The Hornby SR Merchant Navy Class model, 21C1 'Channel Packet', is a highly detailed OO gauge representation of the iconic locomotive. The model measures 362mm in length and features a 5-pole skew-wound motor for smooth running. The recommended minimum radius curve is 438mm, allowing for a range of layout possibilities.

This model is decorated in SR Malachite Green livery and features a high level of detail, including a fully decorated backhead, instrument dials, and a removable simulated coal load with a fully detailed tender bunker. The model also includes accurately modelled Merchant Navy Bullied-Firth-Brown wheels, a cast trailing truck, and separately fitted nameplate, number plate, and company ownership plate.

The electronics and traction features of the model include a pre-fitted steam generator system, which uses optical sensors and piezo element technology to create a realistic steam effect. The system is powered by a cold water-based system, eliminating the need for a heating element. The model also features a pre-fitted 21-pin HM7000 decoder and speaker, as well as a pre-installed Merchant Navy sound profile.

The model requires a DCC controller or the HM7000 app to control, and features a range of adjustable settings, including steam output settings and wheel speed. The model also includes a water reservoir, die-cast connecting rods and valve gear, oilite main drive bearings, and wheel pickups on the tender and driven locomotive wheelsets.

The Hornby SR Merchant Navy Class model is a highly detailed and accurate representation of the iconic locomotive, and is suitable for any OO gauge layout. The model is available in a range of livery options, and is a must-have for any model railway enthusiast.

The model is based on extensive research and original works drawings, and features a high level of accuracy and detail. The Merchant Navy Class was designed by Oliver Bulleid and built by the Southern Railway, with the first locomotive, 21C1 'Channel Packet', entering service in 1941. The model is a great addition to any model railway layout, and is sure to provide hours of entertainment for enthusiasts and modellers alike.

The model is suitable for layouts representing the Big Four era, which includes the LNER, LMS, GWR, and SR, and is available in a range of liveries and configurations.
