NR TA has employed Synergy Rail to undertake preliminary safety and technical business analysis to obtain funding and subsequently to lead the development of the OTTO system and sub-system specification that will be used to procure a prototype system for product approval and pilot application. This engagement followed the successful completion of the RBLS System Specification Development which formed the basis for the work on OTTO.
