The fitted delay lognormal probability density functions of two railway types

Railway type	Lognormal probability density functions	t_0.9 (min)	t_0.95 (min)
Normal-speed railway	$f_{} (t) = \frac{1}{0. 4249 \times t \sqrt{2 π}} e^{- \frac{1}{2} {(\frac{\ln t - 3. 163}{0. 4249})}^{2}}$	41	48
High-speed railway	$f_{} (t) = \frac{1}{0.6319 \times t \sqrt{2 π}} e^{- \frac{1}{2} {(\frac{\ln t - 3.739}{0.6319})}^{2}}$	95	119
