The US trade embargo is a matter of law, and only Congress can repeal it. Do not look for a Republican congress to change the law as long as a Democratic president is in the White House. Yes, Nixon opened relations with China, but in the current political environment, don't look for anything like that to happen.
Regarding second hand US locos in Cuba. There are only two or three survivors and they are standard gauge. There are only a handful of 3 foot gauge locos left and none are second hand. There are still a number of 30" gauge locos that have been preserved, but again, none are second hand.
Get a copy of "Industrial Steam Locomotive of Cuba" which will give you a list of what was still in existence in 1996. Expect considerable scrapping since then.
See this article on locos offered for sale in 2004.
