'We are anxious to communicate with these audiences – our train and station staff work across a large distance and cover different shifts,' LU head of comms Andrew Jones told PRWeek.
It is not yet known where or how many TVs would be installed, but broadcast material would include operational updates and news from around the Tube network, focusing on performance and safety, according to Jones .
The system is likely to be piloted before full rollout.
'We need to measure if staff want information to be delivered in this way, to make sure it is an efficient system and that we would get a return on investment,' Jones explained.
Such a system is already used by employers such as high-street bank HSBC to communicate with staff.
Internal comms methods currently used by LU include monthly magazine On the Move and weekly 'cascade briefings' via a
core team of 100 so-called 'comms champions' – who are responsible for answering staff queries.
* Audit Commission external comms officer Ruben Govinden is to be seconded to the Transport for London press office over the next six months to operate a broadcast desk.
The additional desk is being created to help deal with the predicted increase in media activity generated by the 2012 Olympics and the Crossrail project.
