"The Big Bang Theory" season 8 spoilers hinted that Sheldon did really get on the train, the next question, however, is hard to answer. Where will he go? Meanwhile, Simon Helberg and Kunal Nayyar are on board after agreeing to new contracts.

According to the latest "The Big Bang Theory" season 8 spoilers for fans who are "curious about Sheldon's whereabouts all summer."

"I can confirm that he did, in fact, get on that train (vs. just squatting in the station, as some have speculated)," he said.

"The bigger question you should be asking yourself is whether he ever stepped foot outside the train during his epic journey," Michael Ausiello asked.

There's no answer to that question just yet, as production is only set to start following the signing of contracts by the three major stars of the show, Jim Parsons, Kaley Cuoco and Johnny Galecki. More "The Big Bang Theory" season 8 spoilers will be expected from hereon.

Meanwhile, Simon Helberg and Kunal Nayyar have managed to fulfill their goal of closing the salary gap with the major stars asDeadline reported that the new contract will net them around $70 million each in three years.

According to the website, the deal was struck at the last minute because Warner Bros. TV wanted to meet its production start goal after already releasing a statement.

"Production on season 8 of The Big Bang Theory will begin Wednesday, August 6, with contract negotiations now having been concluded," WBTV just said in a statement.

Nellie Andreeva wrote for Deadline: "I hear each of them (Simon Helberg and Kunal Nayyar) netted more than $70 million over the life of the three-year deals for Seasons 8-10, or 72 episodes. (Each season of Big Bang consists of 24 episodes.)"

"I hear that the quintet all have parity on the back-end participation (more than a point each), which is very valuable, and that Helberg and Nayyar will catch up with their counterparts on per-episode fees in Season 10," Nellie Andreeva added.
