The last steam locomotive ever built for the Union Pacific Railroad is on public display in Shreveport.  Old Number 844 chugged into UP's Hollywood Yard around mid-morning yesterday (Tuesday) and will be here until tomorrow (Thursday) morning.  The big steam engine is traveling across the country to mark the railroad's 150th anniversary.  From here, it heads south to Timpson, Texas.  Number 844 was delivered to UP in 1944 and was almost scrapped when it was no longer used.  But it was saved from that fate in 1960, restored, and now serves as a reminder of times gone by.  The Hollywood Yard is accessible from East Jewella.
