A transport ministry panel said Thursday that it will issue proposals mainly to ensure trains don't run at unsafe speeds, after the deadly derailment on West Japan Railway Co.'s Fukuchiyama Line in April.

The proposals are part of an interim report by the Aircraft and Railway Accidents Investigation Commission, which has been probing the train crash in Amagasaki, Hyogo Prefecture, that killed 107 people and injured more than 500 others on April 25.

The panel will announce details of the report after submitting it Tuesday to Land, Infrastructure and Transport Minister Kazuo Kitagawa.
