I'm so thrilled!!! I just booked my train ticket on rzd.ru website which has recently enabled an English version for travelers. The transaction went smoothly and I had no issues with the visa verified check either (used an Australian card).
I however had Ebertsj step by step guide handy just in case but didn't have to use it in the end.
For those booking your travels shortly, please note that you will have to manually enter your seat number as there is no seat map to select anymore (just open another tab to view the cabin layout and check which seat you would like prior).
You will of course have to register and login first to complete your transaction. I cannot comment on whether the registration part is also in English as I had registered prior to that using Ebertsj cheat sheets- Thank you Ebertsj :))
Good luck everyone!
