unless it is consigned for delivery and unloaded on a private track (see 

Sec. 171.8 of this subchapter). However, if a private track is not 

available, it may be delivered and unloaded on carrier tracks subject to 

the following conditions:

    (1) A tank car of DOT-106A or 110A type (Sec. 179.300 or Sec. 

179.301 of this subchapter) may not be delivered and the loaded unit 

tanks may not be removed from the car frame on carrier tracks. However, 

a carrier may give permission for the unloading of these containers on 

carrier tracks only if a private siding is not available within a 

reasonable trucking distance of the final destination. In addition, 

before the car is accepted for transportation, the shipper must obtain 

from the delivering carrier and file with the originating carrier, 

written permission for the removal and the consignee must furnish an 

adequately strong mechanical hoist by which the tanks can be lifted from 

the car and deposited directly upon vehicles furnished by the consignee 

for immediate removal from carrier property.

    (2) The following tank cars may not be delivered and unloaded on 

carrier tracks unless the lading is piped directly from the car to 

permanent storage tanks of sufficient capacity to receive the entire 

contents of the car; however, such cars may be stored on a private track 

(see Sec. 171.8 of this subchapter) or on carrier tracks designated by 

the carrier for such storage:

    (i) A tank car containing Division 2.1 (flammable gas) material that 

is a cryogenic liquid; or

    (ii) A tank car, except for a DOT-106A or 110A multi-unit tank car 

tank (Sec. 179.300 or Sec. 179.301 of this subchapter), containing 

anhydrous ammonia; hydrogen chloride, refrigerated liquid; hydrocarbon 

gas, liquefied; or liquefied petroleum gas; and having interior pipes 

for liquid and gas discharge valves equipped with check valves.
