The Khalid Abdullah-owned colt has created a big impression in winning his first two races.
“In the Railway, we run Siskin. We didn’t bother going to Ascot and I’d like to think the drying ground (will suit),” said Lyons.
Aidan O'Brien has an incredible record in the race having won it 13 times and he needs one more to draw level with the great Vincent O’Brien.
Monarch Of Egypt, a son of Triple Crown winner American Pharoah, was O’Brien’s first juvenile runner of the season at Naas in April and won easily.
He then suffered a setback which ruled him out of Ascot, but is ready to return now.
“We’re thinking of Monarch Of Egypt for the Railway. He had a little setback which meant he missed Ascot and he’s just ready to start back, but he might go there,” said O’Brien.
