Extra 8421East is entering Alturas on May 13, 1973. The lead unit will be taken off the point and added to engines 9184 and 9228 in the yard. These three units will then be cut in two thirds deep to serve as the helper to get the train up the hill to Sage Hen.
By timetable the train has become No. 560. The lead unit is now 8953. Train 560 is leaving Alturas and making good time toward Likely. You can see the smoke from the helpers further back in the train behind the twin telephone poles. Disk 21
