This document gives guidance on the appraisal of rail interventions.
This Transport Analysis Guidance (TAG) unit was updated in December 2015 to clarify the 3 sources of potential indirect tax impacts in rail appraisals, from changes in (a) fare revenues / expenditure; (b) car use as a result of mode shift; and (c) rail diesel use; and that (a) — the impact from changes in car use — should be calculated as part of the ‘marginal external cost’ method.
The previous version of this unit was TAG unit A5-3 rail appraisal, November 2014.
WebTAG provides information on the role of transport modelling and appraisal, and how the transport appraisal process supports the development of investment decisions and business cases.
