Three photos of SP 8336 set up to take movies for an engineer training program. These three photos were taken at the Santa Fe depot in Flagstaff, AZ during the time when the SPSF merger was still brewing. These photos were taken in the dead of winter and the SP 8336 filmed from Flagstaff up to the Arizona Divide at Riordan. Unit was lashed up to AT&SF 5161 in merger colors. 8336

Although UP officially states; it is not repainting any SP units with SP inspired paint - it sure looks like these are repainted...

(C) Alan Radecki - tunnel motor at sunrise
© Alan Radecki. An 'atmospheric' shot of a SD40T-2 at sunrise, showing the trademark of the tunnel motors - the see-through area below the top mounted rear radiator section.

SP Tunnel Motors came in many variations, short and long nose versions, with and without Locotrol, with and without exhaust silencers and bulged dynamic brake blisters, roof or underframe mounted bells and horn placement. (see table) and the photos.

Yunchi Hsaio recently brought to my attention that, there appears to be one order of short nose that received roof mounted bells, 8489 to 8498.

The post 1980 build Tunnel Motors came equipped with a 'Q' exhaust silencer to meet noise pollution requirements. This required a modified blister at the front of the dynamic brake, (I think for the dynamic brake contactors).

see here for detail shots of the modified dynamic brake blister: SD40T-2 Detail
