    Brief

    Network Rail is seeking suppliers to join Track Work alliances for comprehensive railway maintenance and renewal services. The contracts involve end-to-end delivery including design, planning, installation, testing, commissioning, and project closeout. Primary work includes plain line track, switches and crossings (S&C), and drainage systems. Secondary services may encompass signalling, electrification, plant, telecommunications, civil works, structures, and earthworks, which can be delivered as standalone projects or alongside primary track work through regional frameworks. The alliances will have flexibility to deliver additional standalone signalling and electrification works independent of track renewal projects. Mobilisation is scheduled for mid-2028 with operational launch in mid-2029. This is a multi-year engagement covering Financial Periods 1 and 2. Specific scope details and commercial terms will be provided in tender documentation. Suppliers should have capability in track infrastructure delivery and experience working within alliance partnership models.
