DAX - Date variable with blanks

I will try to explain in the best way possible what I need. So basically I have a calculated column from two other date columns, the "Off Rail" and "Rail Arrived", and like the dates of these columns have to respect an order, the off rail must happen before the rail arrived. The new columns must do these two checks:

 

1) Check if the Off Rail date happened before the Rail Arrived

2) Check if one of those values is BLANK

3) I'm having an issue regarding when these two dates are the same because if they are the same it's OK, but my formula does not return it, I wonder if the problem is at the less than or equal operator when I compare the dates between these two columns 

 

I've created a formula, but I'm not sure if it is in the proper context. I'd appreciate it if someone could take a look at it:

 

RAIL ARVD > OFF RAIL =

VAR Days = IF(

         NOT(ISBLANK(Plan[Rail Arrived])),
         DATEDIFF(Plan[Off Rail], Plan[Rail Arrived], DAY),
         BLANK()

         )

VAR SEBLANK = IF(NOT(ISBLANK(Days)), "OK", "CHECK")

VAR SEDATE = IF(Days <= 0, "CHECK", "OK")

VAR FINAL = IF(SEBLANK = SEDATE, "OK", "CHECK")

RETURN

FINAL

    So I tried but it still didn't solve the problem of the same dates, but your idea helped me to implement this new formula, I run some tests and apparently it is working now, thanks for the help tamerj1 

     

    RAIL ARVD > OFF RAIL =

    VAR SEBLANK = IF(
                    ISBLANK(Plan[Rail Arrived]), "CHECK",
                    "OK"
                    )

    VAR SEDATA = IF(
                    INT(DATEDIFF(Plan[Rail Arrived], Plan[Off Rail],DAY)) > 1, "CHECK",
                    "OK"
                   )

    VAR FINAL = IF(
                    OR(SEBLANK = "CHECK", SEDATA = "CHECK"),
                    "CHECK", "OK"
                  )
                     
    RETURN
    FINAL

    Hi Anonymous 

    please try

    =
    IF (
    Plan[Rail Arrived] = BLANK (),
    "Check",
    IF ( INT ( Plan[Off Rail] - Plan[Rail Arrived] ) >= 1, "Ok", "Check" )
    )
