Many British freight trains formerly had no continuous brake  so the only available brakes were those on the locomotive
Locomotive
A locomotive is a railway vehicle that provides the motive power for a train. The word originates from the Latin loco – "from a place", ablative of locus, "place" + Medieval Latin motivus, "causing motion", and is a shortened form of the term locomotive engine, first used in the early 19th...

Origin

Railways were a formalised development of industrial tramways, which had found need on occasions to add additional braking capacity by adding an empty truck to the rear of a group of tramcars. This allowed the "locomotive" — often a cableway powered by a steam engine at the surface — to operate both safely and more importantly at higher speed.

The first railways, such as the pioneering Liverpool and Manchester Railway
Liverpool and Manchester Railway
The Liverpool and Manchester Railway was the world's first inter-city passenger railway in which all the trains were timetabled and were hauled for most of the distance solely by steam locomotives. The line opened on 15 September 1830 and ran between the cities of Liverpool and Manchester in North...

, one at each corner on the ends, which are pulled together and compressed by the coupling device. With no continuous brake across the entire train, and hence the whole train reliant on the braking capacity of the locomotive, train lengths were restricted.

To allow for longer length trains, early railway companies from the 1840s onwards began replicating industrial tramway practises, by adding "break vans." The term was derived from their name on the industrial tramways, in which they controlled the (residual) train if there was a "break" in the linkage to the locomotive. Early railway couplings

 had been found to be prone to breakages. The term was only replaced by "brake van" from the 1870s onwards.

Because of the combined risks of shortage of brake power and breaking couplings, the speed of freight trains was initially restricted to 25 mph (40 km/h). The brake van was marshalled at the rear of the train, and served two purposes:
  • Provided additional braking for 'unfitted' goods trains
  • Put a man (the guard) at the rear of the train, who could take action in the event of a breakdown or accident.


While the UK railway system persisted until post-privatisation in 1947 with "unfitted" (non-continuosly braked) trains and inefficient couplings, other systems — such as the North American adoption of the Janney coupler

 — overcame the same railway safety issues in a different manner.

The Guard's job

On unfitted trains, the brake van has several purposes, and hence jobs for the guard.

Firstly, and most importantly, the guard would use the brake van's brakes to assist with keeping the train under control on downwards gradients and whenever he could see that the locomotive's crew was attempting to slow the train. Route knowledge would allow the guard to initiate the braking before the driver. To aid in this, signalling regulations mandated that signals be left at clear until the entirety of a train (including guard's van) had passed, as the guard would immediately apply brakes upon seeing a signal at danger.

Secondly, the wheel handbrake could be screwed down to keep the loose screw couplings taut between unfitted wagons, to minimise the risk of snapped broken couplings from the locomotive "snatching" or jerking, which was particularly a problem as locomotives became more powerful. As breaking couplings on unfitted trains when starting were a fairly common occurrence, train crews were given specific instruction. Upon starting a freight train, rules mandated that footplate crew look back on their train towards the brake van, waiting for the guard to signal (by flag or lamp) that the entire train was moving and that all couplings were taut, before accelerating to higher speeds.

A later job of the guard was the provision of side lamps on brake vans. All three side lamps are visible in this picture: the white lamp is the tail lamp, whilst the grey lamps are the side lamps, along with the standard tail lamp (showing red to the rear and sides) required on the rear of every train. The side lamps showed a white light towards the front and a red light to the side/rear. The front-facing lamps were an indication to the locomotive crew that the train was still complete, whilst the provision of extra red lights to the rear was an additional safety measure. Due to the very low chance of all three lights being out at once, it was stipulated that a freight train passing without any lamps on the rear had split and that the rear portion was potentially running away.

, freight trains without a continuous train braking system in either the whole train or the rearmost section of the train ("unfitted" or "partly fitted" respectively in UK railway parlance) were still prevalent in the 1970s but mostly eliminated by the 1980s.

Early break vans were heavily weighted and adapted open freight wagons, equipped with an externally mounted hand-operated brake acting on all four wheels. The term brake van began to be adopted from the 1870s onwards, when bespoke designed vehicles had a specific hut added to house the guard away from the weather. In keeping with tradition, most brake vans had an open area, but from the 1870s onwards this "veranda" became in part enclosed through the addition of a roof. Some vans became fully enclosed, but were equipped at each end with windows to allow the guard to view the entire train.

All of the operating equipment, specifically the brakes and sand boxes to improve traction, were located in the open area of the bake van. Brakes were normally controlled using a hand wheel mounted within the veranda, although some early designs continued with an externally-mounted shaft. To improve the guard's visibility, many were fitted with look-outs on the roof, but side look-outs (termed "duckets") were the more common. The North Eastern Railway

 had reduced by two-thirds the amount of trackage in the UK; resultantly, most steam locomotives had been withdrawn; and most British Railways standard-design diesel and electric locomotives had double-ended cabs. Therefore there was no operational need for so many brake vans, and many types were withdrawn. In 1985 rail unions agreed to single man operation of some freight trains, the first time trains had not had a guard on board for over one hundred and fifty years. Brake vans were still required on trains carrying dangerous chemicals up to the late 1990s.

Australia

In Australia, brake vans (or guard's vans; both terms were in common use) were often also used for carrying parcels and light freight and usually had large compartments and loading doors for such items. Some of the larger vans also included a compartment for passengers travelling on goods services or drovers travelling with their livestock.

, brake vans are still in use to a great extent on passenger trains and goods trains (freight trains). The brake van in the passenger trains (usually the first and last coaches in the train) is a part of a coach and consists of an enclosed room/cabin with two small seats faced opposite to each other, one seat having the writing table for the guard to assist writing and working his train, the opposite seat being a spare. The van also comprises a small lavatory. A special feature of the passenger brake van is a small dog box where a passenger can carry their pet along with them while they travel in the same train in a different coach. The guard generally remains responsible for the water and pet food while the train is moving, and there are features to the dog box to allow the same. The brake van also contains a stretcher, ETL box (Emergency Train Lighting), a stand to hold the lamp signal during the night. The vacuum or air pressure gauge is hosted in front of the guard's seat with a lever to operate it in case of emergency. There is a hand brake which can be used in case of high emergency. The remaining part of the coach consists of space for carrying parcels and small goods. It also has seating for ladies or for the disabled (wheelchair friendly).

The goods brake van in India is less attractive, is generally the last bogie on the train, open on both sides, does not necessarily have interior lighting/lamps, but it does house a small WC lavatory seat for the guard owing to their long hours on freight trains. The van is less secure and has fewer features than the passenger brake van. Eight-wheeled brake vans were introduced recently to improve the riding comfort for the guards.

Passenger brake van

A passenger brake van originally served the same purpose as a goods brake van, but, when continuous brakes became standard on passenger trains, its use changed. The hand brake is still fitted but is for emergency use, and for when the train is parked without a locomotive present. The vehicle also provides a compartment for the guard, a luggage compartment, and sometimes passenger accommodation as well.
