More on the AZL Z Scale Southern Pacific Line Heavyweight Passenger Cars. On an earlier post we highlighted the the Sunset Limited 10 Car St from AZL but at the same time they released a bunch of heavyweight passenger cars for z scale in SP road name. 2 new body styles were added, an observation and a mail car. All told with the different road numbers and car names released, I counted 25 different heavyweight passenger cars, not counting the 10 in the 10 car set. You can see all the cars including the Z Scale Southern Pacific Observation Car, the Z Scale Southern Pacific Mail Cars and all the new releases at Zgauge.Com .There is also buzzing about another new locomotive release….we will post pictures as soon as we see it.
