I've purchased a global pass and am intending to use the first and last days as my outbound and inbound home country days.
Does anyone know if the routing guide applies to these tickets and if a break of journey is allowed?
On my return I will arrive at St Pancrss and need to travel to Leicester. The MML is shut that day so can I go Euston to Nuneaton then to Leicester?
The routeing guide doesn't apply. What you plan to do is fine.
There are
some constraints for home country travel, however, as set out in para 5.2 of the conditions of use
"5.2 Travel in Country of Residence with an Interrail Pass
The Interrail Pass has a specific convenient price which assumes that you are traveling
abroad to experience Europe. Therefore the product cannot be used extensively in your
country of residence since the pricing for such a usage, in some countries, would be
higher. In case of extensive misuse, the railways would decide to increase globally the
price of the product which would be unfair towards the travellers who really want to
experience Europe. In case a ticket inspector observes misuse of this condition, e.g. in
case of frequent travels from and to the same destination, he/she can issue a fine and
ask for blocking of the Pass to limit further usage.
An Interrail Global Pass may only be used for two specific journeys in the country of
residence of the traveller (provided this country is an Interrail participating country).
These two journeys are referred to as the outbound and inbound journey.
• The outbound journey can be used to travel from any location in the country of
residence to the border or an airport or port.
• The inbound journey can be used to travel from the border or an airport or port
back to any location in the country of residence.
During these outbound or inbound journeys, the traveller may travel with more than one
train, provided these train rides are within the same day. Please note that the special rule
for travel with an overnight train also applies. In order to make use of these outbound or
inbound journeys with a paper Interrail Pass, the traveller must indicate the relevant
date and journey on the Interrail Pass Cover and on the Travel Calendar on the ticket. In
case of a Flexi Pass (see also § 3.2)..."
So, it's not intended to be quite as flexible as implied in posts #2 and #3 ( although enforcement might be another question.)
