SR Diagram 1529 / 1530 Cattle Wagons
The first Southern Railway designed standard cattle truck appeared in 1930, earlier SR vehicles being built to pre-grouping designs. The vehicles to diagram 1529 departed from the traditional use of timber on cattle wagon underframes being of an all steel construction, however their routes could be traced back to the SECR. They had a 10ft 6in wheelbase, 8 shoe vacuum brakes with Maunsell brakegear and a handbrake between the wheels.
In 1947 the design was updated with plywood ends, internally reinforced with metal and sheet aluminium roofs. The braking was also altered by Bullied; the handbrake lever being repositioned to the extreme end of the wagon reputedly to avoid the mechanism being clogged up by faecal matter! 101 vehicles to order A3219 were built with through vacuum pipes only, though some were later fitted with vacuum cylinders.
The 2mm Scale Association produces a injection moulded plastic kit that can build either the diagram 1529 or 1530 design. An etched chassis kit can also produce the Maunsell brakegear for the diagram 1529 or the Bullied design for diagram 1530.

Recipe
1 |
Cut out the underframe etch (part 1) from the fret. If the underframe is to be used
with a body kit including bufferbeams, remove the inner bufferbeams from the
etch, and shorten the underframe to match the body. |

1.
2. Bearing cups may be soldered in place before or after folding the underframe into
a U section, according to preference. Fold up the underframe sides into a U
shape. Fit the wheels into the underframe and adjust for free running without
excessive slop. Remove the wheels.
3. If fitting DG or similar couplings, foldup boxes are provided as mounting points.
4. Cut out the combined inner and outer solebar etches (parts 4). The outer solebar
is provided with a selection of drop bars. According to the prototype selected,
remove those not required, and carefully bend those left into an S shape (see
prototype photos. Fold the inner solebar thorugh 180 degress to sit behind the
outer solebar, solder in place, and file off the tabs. Shorten the solebars to match
the underframe length if needed. If cast axleboxes and springs are preferred,
remove the etched ones provided. Now fit the inner and outer solebars to the
underframe, using the bearing cups as locating lugs. Note that the solebars are
handed, and the words �Left� and �Right� are etched onto the solebar and
underframe to assist with this. For the Bulleid Cattle Wagon underframe, separate
outer solebars (part 4B) are provided.
5. Fold up and solder the axlebox etches (parts 5), file of the remining tab, and
locate in place. Ensure you have them nice and squre. Spares are provided in the
case of mishap.
6. If bufferbeams are being fitted, fold up the inner bufferbeams on the underframe.
Select square (part 7) or angle ended (part 6) bufferbeams as appropriate, and
solder into place, ensuring they are accurately located over the buffer holes, and
that the etched channel section faces inwards.
7. For Maunsell or Buleid brakes, cut out fold up the clasp brake etch (part 2),
including the two centrally located tabs, and solder in place in the underframe.
Note the tabs are handled to ensure correct orientation. Fold up the two brake
stretchers (part 10) into an inverted top hat shape, and spring into place between
the brake blocks.
8. For Monarch brakes, cut out and fold up the brake gear (part 2). Solder the
brakegear in place on the underframe.
9. Insert the wheels, and check that they do not foul the brakegear. Remove them
again.
10. Solder the vacuum cylinder in the hole provided.
11. Thread 0.3mm brass wire though the V Hangers, making sure you include the
appropriate brake rodding (parts 11 for Maunsell underframe, parts 11B for
Bulleid) and vacuum cylinder linkage (part 9, (9B for Bulleid only). Leave
sufficient rod protruding to attach the brake levers later. Carefully solder the
various parts in place.
12. Fold up the brake levers (parts 8, or 8B for the bullied underframe). Small location
pips are etched on the levers where bends are required. First form the main
profile of the lever � guides are found on the etch to assist with this. Next fold up
the brake lever ratchet into a box shape. Finally for Monarch brakes fold the
linkage to the V hanger. This is best done over a scrap of nickel silver sheet,
such as the underframe etch surround itself. Now solder the brake levers in place
onto the rod protruding form the V hanger, and into the slots provided in the
solebar. Trim off the excess brass rod.
