High fidelity crushed and graded dark grey limestone ballast analogue. Providing for exacting realism and the ability to create without compromise.
Developed and Manufactured in the UK.

Primary Colour and Source: Dark grey limestone, the mainstay for track ballast for the Northern Railways both pre-war and into the 1960's. Typically sourced from Pennine limestone quarries from Matlock to Teesdale. Whilst material from the Lancashire quarries was a naturally black in colour, pollution and weathering soon turned the lighter coloured limestones from the Southern Pennine quarries a darker colour.

This product also provides a high fidelity analogue for blast furnace slag sourced from steel works across the UK from South Wales (Port Talbot), the Midlands (Ettingshall, Round Oak and Shelton) to the North East (Renishaw and Redcar) and Southern Scotland.

Locally boiler clinker was used for ballast and this product provides an excellent miniature analogue.

Actual Grain Size: 0.35-0.7mm
High Fidelity Analogue at OO/HO Gauge to real life 30-50mm rail ballast.

Pack size: 4kg

Description:
Wave goodbye to generic, one size fits all options and embrace the exacting detail that defines the ultra realism of our high fidelity crushed and graded brown / grey model making granite analogue.

Our meticulously crafted limestone analogue not only adds authenticity to retro and fantasy landscapes but becomes a critical element in the storytelling process. We pay the utmost attention throughout our unique manufacturing process to ensure that the product you receive is free from dust, thus allowing you to create without compromise and providing you with the material to create a sensory experience that transcends its miniature scale.

Colours, textures and most importantly the "true to scale" size of our Ultra Realistic Graded Limestone Analogue are all carefully chosen, ensuring that the stone reflects the diversity of actual applications and imagined Empires and Worlds.

Model railway enthusiasts, enhance the aesthetic appeal of your model railway and impress fellow enthusiasts with the attention to detail that sets your layout apart. Browse our full range of aggregate analogue options, unleash your creativity and let the realism roll!

Using Model Railway Nomenclature, Applications for Limestone Analogue - Dark Grey Include:

Real life examples rounded to nearest actual quarried sizes.

Z Scale (1:220): Real life 100 to 150mm crushed limestone - River Embankment Protection. Often referred to in the construction industry as "rip-rap". Gabion fill and broken stone scree.

N Scale (1:148): Real life 60-100mm crushed limestone - Natural Scree. Badland scaping for gaming scenics.

TT Scale (1:120): Real life 50-80mm fragmented concrete - Urban Apocalypse. The perfect disaster analogue for wargame scaping.

OO/HO Scale (1:76): Real Life 30-50mm crushed limestone track ballast

Railway Board Standard 1246 Aggregates for Rail Ballast, specifies hard, clean and durable stone crushed and graded to 30-50mm. Stone specified to be free of weathered particles, organic matter and inorganic residues - just like our crushed granite analogue only in miniature !

Whilst our crushed limestone analogue makes for perfectly scaled track support, it can also be used for wagon fill and loco shed stockpiles. Whilst track ballast is now predominantly sourced from granite quarries, hundreds of thousands of tonnes of ballast continue to be transported each year by rail from quarries for use by permanent way maintenance crews.

O Scale (1:43): 20-30mm crushed stone - Drainage Ditches, quarry and stockpiles. An ideal matt dark grey modelling background for film and image sets and gaming badland scenics.

G Scale (1:22): 10-20mm Concrete Aggregate. In the real world the largest single application for aggregates. Our crushed granite analoge can be bound with cement, but does not provide for great strength in thin sections. Try epoxy or polyurethane resins or PVA glue to increase strength, or use as a dust free filler/extender in Jesmonite®.

Colour & Form:
We take great care to provide accurate images, however, shade variations can occur both with the products themselves and with ambient lighting.

When used for modelling, perceived variance to colour and reflectance can occur due to base materials and adhesives used.

It can be difficult to adequately describe and visualise grain size, we do, however, show products in context with additional images.

Delivery:
