Editing GE U36B (section)

== Design ==
General Electric's "high-horsepower" universal series locomotives were built around improvements to the 16-cylinder [[GE FDL-16]] prime mover.<ref>{{Harvnb|Pinkepank|Marre|1979|p=40}}</ref> The U36B, rated at {{convert|3600|hp|MW|abbr=on}}, was the most powerful of the four-axle universal series and the last such design.<ref name="Wilson-2017-100">{{Harvnb|Wilson|2017|p=100}}</ref> It was visually indistinguishable from the [[GE U33B]], both of which were {{convert|60|ft|2|in|m}} long.<ref>{{Harvnb|Foster|1996|p=44}}</ref> The locomotives rode on [[Blomberg B|Blomberg trucks]] from traded-in EMD general-purpose (GP) locomotives.<ref>{{Harvnb|Pinkepank|Marre|1979|p=43}}</ref> Each locomotive weighed {{convert|270000|lb|kg}}.<ref name="ftu-20171110">{{cite news | last=Strickland | first=Sandy | title=Call Box: Train was 'Spirit of 1776' | newspaper=[[Florida Times-Union]] | date=November 10, 2017 | url=https://www.jacksonville.com/news/metro/call-box/2017-11-10/call-box-train-was-spirit-1776 | access-date=November 30, 2019}}</ref> The U36B shared large "bat-wing" radiators with other high-horsepower locomotives of its generation at the back.<ref>{{Harvnb|Solomon|2014|p=87}}</ref>

The Seaboard locomotives had an 81:22 gear ratio, permitting a maximum speed of {{convert|75|mph}}. The U36B and the six-axle [[GE U36C]] were designed to operate with the MATE (Motors for Additional Tractive Effort) [[slug (railroad)|slug]]. The MATE had four traction motors, allowing power from the locomotive to be distributed over a total of eight traction motors for double tractive effort.<ref>{{cite journal | title=More use from high power units | journal=Railway Locomotives and Cars | pages=15–18 | date=September 1970 | issn=0033-8915}}</ref> The Auto-Train locomotives did not have [[steam generator (railroad)|steam generators]] for passenger comfort; this was supplied by a separate steam generator car behind the locomotives.<ref>{{Harvnb|Walker|1972|p=46}}</ref>
