THE US Transportation Research Board has expanded its Ideas Deserving Exploratory Analysis programme to include high-speed rail. Last month TRB invited proposals for ’innovative technologies and concepts’ for ’cost-effective upgrading of current rail systems for safer, faster, more efficient and reliable, and environmentally sound high speed operations.’

Areas being considerered for IDEA-HSR include communications and train control systems, track and structure upgrading, environmental and ergonomic factors, level crossing safety, and rolling stock.
