(4) Incidental trackage rights include the grant of trackage rights by the seller, or the assignment of trackage rights to operate over the line of a third party that occur at the time of the exempt acquisition or operation. This exemption does not apply when a class I railroad abandons a line and another class I railroad then acquires the line in a proposal that would result in a major market extension as defined at § 1180.3(c).
