RDSO-assessed platforms — and 200+ inspection certificates

Our platforms are RDSO assessed, and we hold more than 200 inspection certificates issued since. Consignments opened and checked at dispatch, order after order — and machines built so the documents, serials and test evidence are ready before they are asked for.

The credential

RDSO assessed, and 200+ certificates since

Railway supply runs in two stages. The hardware is assessed by RDSO first, and only then are consignments offered for inspection and certified against it — crate by crate, checked against what was ordered. Our platforms are RDSO assessed, and we hold more than 200 inspection certificates issued since.

The two are worth separating, because they answer different questions. The assessment says the design was examined and accepted. The certificates say it kept being built to that standard, order after order, over years. A vendor can have the first without much of the second; the second is what a buyer is really asking about when they ask whether you have done this before.

What it buys you as a customer is boring and valuable: we already know how the paperwork works. The inspection call, the documents that must travel with the consignment, the serial and firmware records an inspector will ask for, and the difference between a machine that is ready for inspection and one that is merely finished.

What is different

Railway procurement asks questions a commercial buyer does not

A commercial buyer asks what the machine does and what it costs. A railway buyer asks those and then keeps going: what it is made of, where it was made, who inspected it, what happens to it in year seven, and whether the identical unit can still be supplied when the first one fails.

Those questions change the build before they change the price. A platform built from whatever was available that quarter cannot answer the traceability question. A configuration that drifts between orders cannot answer the identical-unit question. And a supplier who has never been through an inspection does not know how long the answer takes to assemble.

So the engineering that matters for railway supply is mostly documentation engineering — recorded baselines, stable configurations, named components — and it has to be designed in from the first order rather than reconstructed at the fourth.

The estate

From the zonal office to the trackside cabinet

Railway deployments are rarely one machine in one room. They are several classes of machine in several kinds of place, and the difference between them is environmental as much as technical.
