Railway components are high-mix, low-volume with frequent revisions, and the buyer expects part-level history. Paper drawings and handwritten logs cannot guarantee current revisions and produce traceability at the same time.
You cannot be sure the drawing on the floor is current
When engineering revises, paper has to be recalled and reissued — with no way to confirm every old copy was retrieved.
02
Assembly and wiring history is not retained
Who completed which operation and when exists only in the logbook.
03
Work instructions change constantly
High-mix, low-volume means per-unit specifications differ and schedules shift.
Where railway components plants get stuck
Problems that come up repeatedly in implementation discussions.
Field issue
You cannot be sure the drawing on the floor is current
When engineering revises, paper has to be recalled and reissued — with no way to confirm every old copy was retrieved. Working to a superseded drawing means rework.
Field issue
Assembly and wiring history is not retained
Who completed which operation and when exists only in the logbook. When an audit or a claim arrives, finding the history for that unit takes days.
Field issue
Work instructions change constantly
High-mix, low-volume means per-unit specifications differ and schedules shift. Paper instructions take time to reach the floor, and work proceeds to the wrong specification in the meantime.
Field issue
Progress is invisible from the office
Finding out which unit is at which operation means walking the floor and asking. Decisions to prioritise a unit against a tight delivery come too late.
What gets connected

Links unit and part, enabling traceability
Build sequence
Nothing is converted all at once. High-impact areas are built and verified first.
STEP 01
Digitise drawings and fix the revision rule
Move drawings to digital and, first, decide what counts as the valid revision. Without that rule, digitising leaves the superseded-drawing problem in place.
STEP 02
Place terminals on the floor
Put a tablet or kiosk at the work position showing only the drawing and instruction for that operation. If it takes several steps to find, it will not be used.
STEP 03
Collect work history
Capture operation completion at the point of work to aggregate per-unit progress live. Reducing the entry burden is the whole of this step.
STEP 04
Connect traceability
Attach part identity and inspection results to the unit so the history a buyer asks for can be produced immediately.
Applied solutions
Scope is composed after reviewing equipment and workflow.
Questions that come up on railway components floors.
Do we have to convert thousands of drawings at once?
No. The usual approach converts units currently in production and items coming up, adding historical drawings as needed. Requiring full conversion up front only delays the start.
Do engineering changes reach the floor automatically?
With a valid-revision rule in place, floor terminals show only the current revision. The biggest change is that nobody has to confirm old copies were recalled.
How do we handle buyer audits?
Because operation completion and inspection results attach to unit and part identity, the history for that unit is produced by query rather than by search.
Will operators actually use tablets?
With entry fields kept minimal and only the relevant operation on screen, the burden is small. The design goal is not adding decisions for the operator to make.
Can it connect to our existing ERP or PDM?
Yes. Items and BOMs come from ERP, drawing revisions from the engineering system, and MES owns execution history — roles divided rather than duplicated.
