This example has been finished with transfers from the Modelmaster Decals range and weathered using acrylic paints and Humbrol weathering powders.

Some kits also feature etched parts for brake gear components and lengths of brass wire to form handrails. The basic principles of building one of these kits are the same as for 4mm versions, but there are a few aspects of construction that are expanded upon in the following step by step sequence. The featured kit is an LMS 20T Goods Brake Van (ref.PS111). STEP 1 STEP 2 Because this model has Following assembly of the handrails, the sides need sides, ends and floor, the preparing prior to assembling couplings can then be added to the body; the holes for the the headstocks.

To fit the coupling, the hook was inserted through the headstock and the spring slotted over from the back. Whilst compressing the spring STEP 3 against the back of the headstock, the ‘tails’ of the hook were bent at opposing right angles to lock the coupling in place. The axleboxes are separate units that are designed to float vertically within the W-irons, STEP 4 intended to offer a degree of The wheelsets are fitted compensation when running with the axleboxes held over uneven trackwork.

Self-adhesive type transfers are supplied in the 7mm range kits, which cover pre-grouping, post-grouping and post-nationalisation eras as appropriate, with a selection of numbers for each. Each transfer is cut round (through the tissue only and not the backing paper) and then picked up and placed in position with tweezers. It is then pressed down on the body before soaking with water. This separates the tissue from the transfer which can then be lifted clear, as illustrated. A pass of matt varnish from an aerosol helps to fix the transfers in place and protect them from handling. Weathering can be undertaken if desired; weathering powders were used on this model. Building a Parkside Models kit can be a very satisfying and rewarding exercise. And with such a wide variety of kits available you will be sure to be able to add new stock to your railway that cannot be found from the ready-to-run manufacturers.
