Two trains are usually joined together on departure from Glasgow, the front train will be heading to Oban and the rear train will be the train travelling to Mallaig via Fort William.
............................................................
To make the most of the train journey from Glasgow to Oban ShowMeTheJourney's recommendation is to be at Queen Street station, ready to board, a minimum of 20 - 30 minutes before departure.
You can then be among the first passengers to step on to the train and seek out spare window seats on the left-hand side -as the overhelming majority of the best views during the journey can be appreciated from that side of the train.
Ignore your seat reservations when you first board, because you may have been assigned seats on the right-hand side - and by the time you have found your seats, the optimum seats over on the left may have been occupied.
The ultimate travel experience when taking the train to Oban, is to have a table seat by the windows on the left, but most of the seats on the train aren't at tables.
The table seats line up with the windows, so they have the best views, which is why such seats on the left are worth seeking out.
The unreserved seats don't have paper labels stuck on them.
You won't have to sit in the seat(s) you have been assigned for your ticket to be valid.
If you've struck lucky and found such seats, you can then take a look as to where your reserved seats are located - if they happen to be the same type of seat, by the table, on the left, then you should move to them instead - it will stop other passengers from assuming that they're not available.
Though particularly in the summer months these can be fairly busy trains, so on Fridays and Saturdays you may be grateful to have assigned seats - even if they happen to be over on the right.

Senic Rating: ****
Step on board for a stunning train ride along the the West Highland Line.
Around 25 minutes into the journey, after the train has departed from Dalmuir (where connections are available with trains from Glasgow Central), the railway begins to travel along the north bank of The Clyde Estuary.
The train wll spend around 20 minutes travelling by the river until it arrives in Helensburgh.
Between Helensburgh and Arrochar & Tarbet there are spectacular views on the left down over two sea lochs - Loch Gare followed by Loch Long.
Between Arroacher & Tarbet and Ardlui, Loch Lommond is over to the right - though the railway is set back from shore, so for most of this part of the journey, the loch can only be glimpsed through the trees.
Since leaving Arroacher & Tarbet the train will have been travelling the Loch Lomond and Trossachs national park and between Adrlui and Tyndrum it is the hills of The Trossachs which surround the train.
ShowMeTheJourney has to own up to the fact that I've yet to experience the part of the journey on from Tyndrum to Oban, but I'm 100% certain that it will be wonderful
After Tyndrum, for the first part of the journey from there to Oban, the best of the views are again on the left.
From that side of the train there will be views over Lochan na Bi and then after Dalmeny the railway is by the shore of Loch Awe.
But for the final 20 minutes of the journey, before and after Connel Ferry station, there are some coastal views to be savoured over on the right.
