We recover the cost of electric current for traction (EC4T) through traction electricity charges, which are charged to all electric train operators

In April 2010 some operators moved to metered electricity billing, also known as on-train metering (OTM), which means their charges are no longer based on modelled consumption rates, but instead are based on actual metered usage.

All published documentation related to on-train metering and the traction electricity rules can be accessed below.

Traction electricity rules (formerly known as the EC4T metering rules)

The traction electricity rules are a common set of rules that apply to all parties who run electrically powered services (with some minor exceptions). The traction electricity rules are incorporated into, and therefore form part of, each track access agreement between Network Rail and operators.

Information on on-train metering incentive charge

We levy an on-train metering (OTM) incentive charge on metered operators where there are significant levels of missing metered data.

The provisions relating to this incentive charge are outlined under paragraph seven of the traction electricity rules.
