Sir - In your article 'ERTMS tests underway' (RG 5.04 p278) you state that AnsaldoBreda is a member of Consorzio Saturno. This is not correct. The members of Consorzio Saturno are Alstom Ferroviaria, Alstom Transport, Ansaldo Trasporti Sistemi Ferroviari, Ansaldo Segnalamento Ferroviario, Balfour Beatty Rail and Sirti.

Sir - In RG 6.04 p321 you reported the award of the contract for construction of Tehran metro Line 4. I should like to advise your readers that the contract value is US$680m, not US$863m as you reported. There will be 160 EMU cars, not 161.
