Another mandatory referendum was held on 19 November 1998 about the creation of funds for four major public-transport projects (, , ), funding them with time-limited CHF 30 billion fund of which the NRLA would receive 13.6 billion. Another major project was the Bahn 2000 project regarding the modernization of the railways. The Federal Council's request was approved with 63.5% support. The fund is replenished primarily by the previously mentioned kilometre-based tax on heavy-goods vehicles (HVF) and partially by taxes on gasoline originally intended for road-building, a small fraction of the VAT revenues, and funds from the general budget of the Swiss Confederation.
