Rail and rolling stock depots: tools, components and people, located where it mattersDepot tools and parts never where they should be?
Independent advice for train operators, rolling-stock owners, maintainers and infrastructure depots: tool control in the sheds, tracking of rotable and repairable components, and knowing who is on which road. We don't sell hardware, so our advice stays independent.

Depot use cases
Tool control and calibration in maintenance sheds
Torque tools, gauges, lifting gear and special tools issued against a work order and returned at shift end, with calibration dates checked at issue. Passive RFID at a store or cabinet is usually enough; live location is rarely needed. See tool control.
Rotable and repairable components
Bogies, wheelsets, couplers, traction and door components that leave a vehicle, go for overhaul and come back. A read at each hand-off keeps the component’s history attached to the right serial number.
Special tools and kits
Kits that travel with a job between depots or to a recovery site. Reads at the depot gate or store show what has left, where it went and whether it came back complete.
Five use cases in rolling stock depots
Wheelsets, bogies and rotables keep their history
Each component identified by serial number at removal, the component shop, overhaul and fitting, so its history is built as the work happens. Serialisation and custody
Units found, and time on depot
Each unit shows which road or siding it is on and when it arrived, so the right unit is pulled for the right exam. Asset tracking
Depot tools in date and back
Tools issued against a work order, blocked if past calibration, and listed if not back before shift end. Tool control
Exam parts ready at the road
Parts for each planned exam picked against the work order and confirmed at the right road before the unit comes in. Parts in sequence
Faulty parts kept apart
Removed and faulty parts marked in the system, kept apart from serviceable stock and flagged if they leave quarantine. Inventory accuracy
Who is on which road, linked to isolation and permit-to-work
In a depot, the safety question is who is on which road or in which shed while vehicles move and lines are live. Location can support the answer, but it must not replace the rules that keep people safe.
- Presence by road and shed, so the shift lead can see who is working where before a move is authorised.
- Linked to isolation and permit-to-work systems, so a permit can show who is inside the protected area, and whether they have left, before it is closed.
- A support, not the control. Physical isolation, protection and sign-off stay as they are; location data adds a check, not a shortcut.
- Agreed with staff and their representatives before anyone wears a tag, with clear rules on what is recorded and who can see it.
Fleet maintenance systems and component records
Each part’s history must sit in the fleet maintenance system, not in a separate locating dashboard. We specify the interfaces first: which read creates or closes a work order step, which updates a component’s location or status, and which is ignored. See CMMS integration.
We survey the site and do the cabling and fit your hardware ourselves. Your IT team provisions the network connections and keeps control of them; we do not configure your networks or run your production systems.
Mixed indoor and outdoor sites
Depots combine sheds full of steel, open sidings and yards, and long approaches. One radio technology rarely fits all of it:
- Sheds and stores: passive RFID for issue, return and hand-off reads; BLE or UWB where live location inside a shed is needed.
- Sidings and yards: GNSS on vehicles and plant, with gate or portal reads where items enter and leave.
- Everywhere: equipment rated for the environment, power where the reader goes, and maintenance access that does not need a possession.
We choose per area and per decision, then test the choice on your depot. See choose a locating technology.
AMRs and AGVs in rolling stock depots
In a depot, waiting for parts and tools holds up the train, not just the job. We help you choose the right AMR or AGV for each run, then check what it takes to run them safely alongside roads, pits and people.
- Parts, tools and consumables moved from stores to the maintenance roads.
- Components and repairables returned to workshops and stores.
- Routes that respect road protection and safe walking routes.
- Charging and uptime planned around shift patterns.
- Robot fleet management: one fleet manager for robots from different manufacturers, shared doors and chargers, and priority for urgent jobs. We check what it takes and help you make it work.
- Integration with your maintenance and stores systems, so moves follow the work order.

Frequently asked questions
Can location tracking replace our permit-to-work process?
No. It can support it, for example by showing who is inside a protected area before a permit is closed, but isolation, protection and sign-off stay as your safety rules require.
Do we need to tag every component?
No. Start with the components and tools where a lost history or a missing item causes real cost or risk, usually rotables, special tools and calibrated equipment. Consumables and low-value parts rarely justify a tag.
Will it work outdoors in sidings and yards?
Yes, with the right mix. GNSS and gate reads usually cover outdoor areas, with RFID, BLE or UWB inside the sheds. We test the mix on your site before you commit.
Who installs the system?
We carry out the RF site survey and install the cabling and hardware ourselves. Occasionally a delivery partner may help, but only with your written agreement and under a written contract. Your IT team provisions the network connections; we do not configure your networks or run your production systems.
Do you sell hardware or maintenance software?
No. We advise, specify, help run the tender and accept the system on your side. You buy hardware and licences direct from the supplier; we don't resell them.
