Eastern Railroad Discussion > What is a Key Train?Date: 05/02/11 09:23 What is a Key Train? Author: IndianaHarbor I occasionally hear crews on the NS Chicago District identifying themselves to the dispatcher as being a "key train". What does this mean? Thank you all in advance.

------------------------------------------------------- > Mostly a Chemical only train. (Haz-Mat) Not at all true. A train can have mostly non-hazardous cars and still be a key train if it meets the following standards (as copied from the site to which I previously linked): a. one (1) or more loads of spent nuclear fuel (SNF) or high level radioactive waste (HLRW) moving under the following Hazardous Materials Response Codes -- 4829135, 4929125, 4929135, 4929140, 4929150 or b. 5 or more loaded tank cars containing materials that require the phrase “Poison-Inhalation Hazard” (Hazard Zone A, B, C, or D on the shipping papers) or anhydrous ammonia (Identification Number 1005) or c. a combination of 20 or more loaded hazardous materials shipments or intermodal portable tank loads of a combination of “Poison-Inhalation Hazard” (Hazard Zone A, B, C, or D on the shipping papers), flammable gas (2.1), anhydrous ammonia (Identification number 1005), Class 1.1 or 1.2 explosives, or environmentally sensitive chemicals (see Table 3).

Grady Date: 05/02/11 20:47 Re: What is a Key Train? Author: kd0086 You are right. That is what I was trying to say in the short form but I should have broken it down.
Date: 05/02/11 22:25 Re: What is a Key Train? Author: djshadowxm81 The new NS Dispatching system known as UTCS classifies any train with a certain amount of haz-mat cars in the consist ( that number I knew then forgot) but it is safe to say trains such as 68Q loaded is a Key Train however its empty counter part is NOT a key train 69Q.
