I just wish that Lionel made a cabless booster unit version of this locomotive so that at least I could have an accurate Southern Pacific version.
THAT'S an excellent suggestion. Has anybody bothered to inform Lionel that, if they offered the original DD35, they could then have the GP35 - DD35 - DD35 - GP35 EMD demonstrator set???? Plus, Union Pacific consists of GP35 - DD35 - DD35 - GP35 consists!
Apparently the thought of selling TWICE AS MUCH PRODUCT to those folks who model the UP, or who would desire a 1963/1964 era EMD demonstrator, hasn't dawned on them.
I have run my UP GP35 and 2 DD35a units in a MU consist and it was amazing. I have attached a couple of pics with one GP35 and one DD35a running on my layout.
