The incident with Tanya Rosenblit seems to be the straw that broke the camels back (Tanya Rosenblit Is The Straw That Broke The Camel's Back) and it is clear that Egged will not be able to continue the Mehadrin bus lines.
Therefore a group of Charedi askanim have come up with a plan to set up free private mehadrin bus lines. Why free? Because by law a private company cannot run a fee for service bus line without a permit from the Ministry of Transport which they won't get. Therefore, to get around this the buses will be free, however, there will be pushkas on the bus for anyone who wishes to contribute.
This is expected to cost 6 million shekel a month. As I wrote here, The real cost of mehadrin standards, you have to question whether this is the best use of such a large sum of money. The Charedi population is very poor (see Poverty in Israel - some disturbing statistics about the Charedi world) and I am sure that the money could be used for more pressing needs then Mehadrin buses.
